Is it cold out there too?
A child getting over a cold on a cold day needs the layers and the icy-ground check as well.

Kit, Rules & Safety
Most children can go back to a gentle kickabout once the illness has clearly passed. That means no high temperature, no chesty cough and a child who is properly themselves again, with a first game that is short, soft and easy.
There is no UK rule on how many days a child must wait before football after a cold or flu. The NHS and UKHSA say a child with a high temperature should stay home until it goes, and that mild cold symptoms in an otherwise well child are not a reason to stay off (NHS, UKHSA). Sports medicine adds a cautious custom: wait a full day after the fever, then start gently (TrueSport). Anything beyond a sniffle, or any worry, goes to your GP or NHS 111.
For a long time I treated "seems fine" as the same as "is fine", and I only saw the difference when a child who had been bouncing all morning was flat on the back step four minutes into a kickabout. I am a dad, not a doctor, so everything below is a starting point to check with your GP, a pharmacist or NHS 111.

When Can My Child Play Football Again After Being Ill? The Short Answer
The NHS says that if a child has a high temperature, you should keep them off school until it goes away. A child with a slight cough or common cold symptoms can go to school, it adds, if they are otherwise well and have no high temperature (the NHS guide to whether a child is too ill for school).
UKHSA says a child with a high temperature should stay at home, and can resume normal activities when they no longer have a high temperature and are otherwise well enough (UKHSA's guidance on children with respiratory symptoms). That guidance is dated June 2022, so it is worth checking for updates.
Both are about school and spreading infection, not about running about, and neither mentions sport. A child who is better, eating, full of energy and begging to play is a different case from one who stopped being feverish an hour ago.
This matters when you are deciding on football after being unwell. No source sets a number of days for football after a cold or flu. The only day counts are a full day fever-free from sports-medicine custom and at least 2 days after sickness or diarrhoea from the NHS and UKHSA. So the table below is keyed to how your child is today, not to the calendar.
A baby, a toddler, a child with a long-term condition or a weakened immune system, or any child you are worried about, goes to the GP first. UKHSA says to seek medical help if you are worried, especially for under 2s. If the answer is not yet, how to end a session without a meltdown helps with the argument.
A rule of thumb, not a rule
The Neck Check: What It Is and What It Does Not Prove
You will see "above the neck" advice everywhere. A runny nose or sore throat is said to be fine to play through. Symptoms below the neck, such as a chesty cough, aches or an upset stomach, mean rest (TrueSport's return-to-sport advice, a US hospital's six signs).
None of the NHS or GOV.UK pages read for this guide mention the neck check. Playing football again after being ill is not something those pages cover.
A chapter in the IOC football return-to-play book calls it "a sign often used in clinical practice, with little scientific evidence". It says an athlete with only a sore throat should rest for the day (the football return-to-play chapter on infectious disease).
A 2024 expert-opinion article in the Journal of Sport and Health Science calls it "nonscientific but may be partly useful" (a 2024 expert-opinion article on sport during viral respiratory illness).
Both papers are about athletes, mostly adults, and neither tested the rule in children. The US sports-medicine pages treat it as settled, and the papers do not.
So the plain use of the rule is this. It is a fair first question for a mild cold, a poor reason to ignore a fever, and never a replacement for looking at the child in front of you.
Decide by today, not the calendar
Return to Play After a Cold or Flu: Play, Light Play, Rest or Ask First
This table is a parent-level guide built from NHS, UKHSA and sports-medicine sources, and your GP, pharmacist or NHS 111 outranks it.
| How your child is today | What to do | Why |
|---|---|---|
| Sniffles or a mild sore throat, no high temperature, eating and playing as usual | Light play is reasonable for sniffles; rest if the throat is sore | The NHS says a child with slight cold symptoms who is otherwise well and has no high temperature can go to school (NHS), and UKHSA says the same (UKHSA). The neck check is weak evidence, and the football return-to-play chapter says an athlete with only a sore throat should rest for the day. So keep any play short, let them stop, and rest if the throat is sore. |
| A high temperature now (38C or more) | Rest at home, no football | The NHS says to keep a child with a high temperature at home, and to get medical advice if you are worried (NHS fever page). Playing on a fever is not something any source here recommends. |
| Fever gone since yesterday, still pale or tired | Wait another day | UKHSA says flu cases should stay away until better and no longer have a temperature (UKHSA), and the NHS describes flu as leaving you too unwell to carry on as normal (NHS flu page). Sports medicine custom, mostly US, is a full day fever-free without fever medicine (University Hospitals). |
| A wet or chesty cough, aches, chills or breathlessness | Rest, and ask a GP or NHS 111 | Sports medicine custom treats symptoms below the neck as a reason to rest. The NHS lists shortness of breath and chest pain as reasons to see a GP (NHS cold page) and difficulty breathing as urgent (NHS cough page). |
| Sick or diarrhoea in the last 2 days | No football yet | The NHS and UKHSA say to stay off until a child has not been sick or had diarrhoea for at least 2 days (NHS diarrhoea and vomiting page). Offer fluids and watch for dehydration. |
| Better, fever gone a day or more, eating, normal energy | First game back: 5 minutes, soft ball, close range | Sports medicine custom is a stepped return over a few days (TrueSport), and the football chapter says to build up only while symptom-free (return-to-play chapter). See the next section. |
| Not their usual self, off their food or you are worried | Not today: call NHS 111 or your GP | The NHS says to contact 111 if a child is not their usual self and you are worried (NHS fever page). Your own worry counts. |
The table is not a countdown, because the same child can sit in two rows in one day. A child who is fully well is still not a reason for a long session on day one.
If it is cold out as well, the cold-weather checklist covers what to wear and when to come in.
Five minutes, easy touch
Resuming Sport After Illness: The First Game Back
This is for a child who is clearly better, and it is not a plan for football after being unwell in general. It applies the stepped return idea in the sports-medicine pages to a kickabout. The figures there, such as starting at about half effort and building over 2 to 7 days, are coaching custom, not tested numbers.
- 1
A look before the ball. Check colour, appetite and mood. If they are not themselves, nothing is played today.
- 2
Five minutes only. Soft ball, close range, no chasing and no shooting at full power. The Slow Roll in the calm bedtime game fits exactly.
- 3
A drink and a seat. Water and a step to sit on within reach, and a break after the first couple of minutes.
- 4
They call time. If they slow down, go quiet or look flat, the game ends there, with no persuading.
- 5
A little more tomorrow. If the session leaves them fine, add a few minutes or a step of distance the next day. For turning a game down or up gently, there is a short guide.
"Shall we do five minutes of slow passes today and you tell me when you've had enough? If it goes well we'll do a bit more tomorrow."
For another quick session idea, try the 5-minute games.
Call, do not play
When It Stops Being a Football Question: NHS 111, a GP or 999
The NHS draws these lines on different pages, so this is what the NHS pages say, not a complete list, and it follows their wording closely.
Call NHS 111 if your child (the NHS page on a high temperature in children):
- has a high temperature that has lasted 5 days or more
- has other signs of illness, such as a rash, as well as a high temperature
- does not want to eat, or is not their usual self and you are worried
- is dehydrated, with signs such as sunken eyes and no tears when crying
For a cough, the NHS says to get urgent help (111 or a same-day GP) for a severe or rapidly worsening cough, feeling very unwell, chest pain or difficulty breathing (the NHS page on a cough).
See a GP (non-urgent) if (the NHS page on the common cold, the cough page):
- a high temperature lasts more than 3 days
- symptoms get worse, or a cold is not better after 10 days
- a cough lasts more than 3 weeks
- you are worried about your child
The 3 and 5 day lines differ between pages, so when you are unsure, ring.
Call 999 if your child (NHS fever page):
- has a stiff neck, or a rash that does not fade when a glass is pressed against it
- is bothered by light, or has a fit for the first time
- has unusually cold hands and feet, or blue, grey, pale or blotchy skin, lips or tongue
- is drowsy and hard to wake, or is extremely agitated or confused
- has difficulty breathing or is breathing very fast
- is not responding as they normally do
The NHS flu page adds sudden chest pain and severe difficulty breathing. If any of these appear, the ball goes away.
What is known and what is not
What the Guidance and the Papers Say, and What They Do Not
The best-sourced statements are about school and infection. Stay home with a high temperature, and mild cold symptoms need not keep a child off (UKHSA's public health exclusion periods for children's settings). These decide who may mix with others, not who is fit to play, and none mentions sport.
The football return-to-play chapter (Borjesson et al. 2017) is an expert narrative chapter with no sample. It says return should follow clearance of the infection and build gradually only while the athlete is symptom-free, and it calls the neck check weakly evidenced (Read the chapter). It was written for elite adult footballers and has no specific child guidance.
A 2024 perspective article (Ruuskanen et al.) is expert opinion with no sample. It says there is a lack of evidence that exercise during a common cold causes significant harm, and that no studies have been done during the acute symptomatic phase of naturally occurring infections (Read the article). It covers athletes, mostly adults, and a mild cold is not a fever, a chesty illness or flu, so it cannot be read as permission for a child.
A review (Martin et al. 2009) describes a lab study in which college-aged adults, deliberately infected with a rhinovirus and asked to exercise moderately, had no worse symptoms than those who did not (a review of exercise and respiratory viral infections). It is a second-hand description with no sample size stated, about adults and a mild cold virus, not flu, fever or children.
The evidence is thin, and the careful reading is caution, not confidence. The 24-hour fever-free rule and the step-up percentages come from US sports-medicine pages, not from the NHS or UKHSA.
Quick answers
Common Questions About Football After Illness
Can my child play football with a cold?
If they have slight cold symptoms, are otherwise well and have no high temperature, the NHS says they can go to school (NHS). Light, short play is reasonable for sniffles, but rest if the throat is sore. A high temperature, a chesty cough or just feeling poorly means rest too. Ask your GP or NHS 111 if unsure.
How long after a fever can my child play sport?
No UK source gives a number of days. US sports-medicine advice is a full day without a fever, and without fever medicine, then a gentle start (TrueSport, University Hospitals). UKHSA says flu cases should stay away until they are better and no longer have a temperature (UKHSA).
What is the neck check for exercise when ill?
It is a rule of thumb. Symptoms only above the neck, such as a runny nose, are said to suit light exercise, and symptoms below the neck mean rest. A football return-to-play chapter says it has little scientific evidence, and a 2024 article calls it nonscientific but possibly partly useful.
Can my child play football after a tummy bug?
Wait until they have not been sick or had diarrhoea for at least 2 days, as the NHS says for school (NHS), and watch for dehydration. Then make the first game short and soft.
How do I know if it is too soon?
If they slow down, go pale or quiet, or want to sit, stop and rest. A child who is not their usual self, or whose symptoms come back, needs a GP or NHS 111 rather than another go (NHS).
When should I call NHS 111, a GP or 999?
The NHS lists 111 for a high temperature lasting 5 days or more, a rash with a high temperature, or a child who is not themselves. It lists 999 for a stiff neck, a rash that does not fade, difficulty breathing or a child who is drowsy and hard to wake (NHS). The red flags section has the full lists.
