AFC Wimbledon boss Neil Ardley has revealed that striker George Oakley could miss the start of the season through injury.
The 18-year-old suffered a hamstring problem during a training session on Friday.
"We've had some bad news with George picking up a hamstring injury when we were doing some work on crossing and finishing in training," Ardley told the club's official website.
"We are fearful that it could mean a few weeks out for George. He was ill for a while and it's been a stuttering start to pre-season in terms of his physicality. We hope that it's not too serious."
AFC Wimbledon return to pre-season action on Friday when they make the trip to Havant & Waterlooville.
