Chelsea star Daniel Sturridge is a major doubt for the Olympics after undergoing emergency treatment for suspected viral meningitis, according to reports in the British press.
Sturridge's condition is said to have improved over the last 48 hours, but his place in the 23-man Great Britain football squad, is clearly in doubt.
The 22-year-old was rushed to St Mary’s Hospital in Paddington after repeatedly vomiting and complaining of severe aches and pains.
A British Olympic Association spokesman said: “We still have some time to assess the situation and wait for the results of Daniel Sturridge’s tests.”
Meningitis sufferers often face a lengthy recovery process and there can be long-term headaches, tiredness and even memory loss.
So the implications for Sturridge could go way beyond the upcoming Olympic Games and well into Chelsea’s pre-season preparations.
Pearce has until July 25 to select a replacement should Sturridge be forced to withdraw.
But immediate concerns revolve around the health of Sturridge, with more details of his condition expected when Chelsea boss Roberto Di Matteo holds a routine pre-season press conference at the club's training ground on Wednesday morning.
Doctors reportedly suspect Sturridge may be suffering from the viral strain of the disease, whose symptoms are generally mild and which can be overcome without the need for medical treatment, according to UK Press Association.
Sue Davie, chief executive of the Meningitis Trust, told Sky Sports News on Tuesday night: "I can't comment on specific cases but if it's viral meningitis it's a less severe form, although it can be very debilitating.
"A sufferer can have symptoms such as headaches, tiredness, a stiff neck, nausea, vomiting and a dislike of bright lights. It can go on for months.
"It can't be treated with antibiotics very much. It's about resting and getting proper care in hospital, being looked after well and making a full recovery.
"But it will take a little while. I would imagine his doctors will say to him he needs to rest and take care."
