Stuart Pearce says Daniel Sturridge still remains doubtful for Team GB's Olympic campaign and has until the end of the week to prove his fitness.
The Chelsea striker has only just returned to training after being treated for viral meningitis, an illness which looked set to rule him out of the Olympic football tournament.
With Great Britain's first game against Senegal just over a week away the 22-year-old doesn't have much time to prove he is fit to represent Team GB.
Pearce's men, who are 11.00 to win Olympic gold, take on Brazil in a friendly on Friday and the former Manchester City manager will make a decision on Sturridge after that game in Middlesbrough.
Pearce says Sturridge's participation is still in the balance, despite Chelsea's medical staff declaring him fit.
"I have got to be 100% sure in my mind that Daniel is fit enough and can see out a tournament," Pearce said.
"There were certainly doubts because of the illness he had
"Our fitness and conditioning people are having a look at him, to see how he will come through training. Chelsea's medical people are more than happy."
Should Sturridge fail to prove he is fit then Pearce can call up a replacement, with Huddersfield Town striker Jordan Rhodes reportedly in the frame to join the 18-man squad.
