Simon Bassey said that Andy Barcham was left out of the squad for the defeat at Plymouth Argyle as a precaution and his fitness will continue to be monitored.
The winger was initially named in the squad on Tuesday night, but he was replaced on the substitutes' bench by Egli Kaja.
Speaking ahead of Wimbledon's home match against Bristol Rovers on Saturday, Simon said: "It is not overly serious, but with Barchy you always know that with a big schedule of games he can struggle because he puts so much effort in. Obviously, the pitches are very difficult at the moment and Bury was very taxing. With all the travelling on the coach, it's not good for his hamstring to be in the same position. We took the precaution of taking him out, rather than leaving him in and taking the risk that he pulls his hamstring and is out for the season. We have to be cautious with it, but I don't see it being overly serious."
Our first-team coach believes that midfielder Dean Parrett will provide a good option after his return as a substitute on Tuesday night, which came after four months out of the first-team picture due to a groin injury.
"He has been out for a long time and it was quite a serious injury," said Simon. "Dean has been back training for four weeks now, but he had a game for the Under-23s, and obviously got minutes the other night. It gives us other options because he does different things than the other players we have got. It is good to have those options. Everyone else is fit, but Will is still not closer. We have got good numbers to pick from."
