Winger could be out for extended spell.
The flying wide man came off in the U's FA Cup game at Chelmsford, and post-match scans have shown that his injury could rule him out for some time.
U's loanee winger Sanchez Watt could be out longer than expected, after it was revealed that his hamstring injury was worse than first feared."Sanchez is a lot worse than we thought, so we will have to deal with that," manager Joe Dunne told the press on Thursday.
"He has been a credit to us, and a credit to Arsenal.
"He wants to stay around and be a part of it here, which is a great credit to him and what we are trying to do here.
"But unfortunately the assessment of the hamstring is worse than we thought. We have possibly seen the last of him for now.
Joe also told the press that he is working on fresh faces before the weekend trip to Crewe.
"Those kind of things you don’t rush back from, because they could have a detrimental effect on a player, especially someone like Sanchez, who is an explosive type of player."
