Tony James, the Hereford United captain, is to see a specialist about his injury after clashing with Gary Ricketts in the Trophy replay. He is currently on crutches and could be out for several weeks if not the rest of the season.
"Tony is seeing a specialist but he's on crutches at the moment and could be out for at least three or four weeks," Graham Turner told the Worcester News.
"There's a possibility that he could be out for the rest of the season but we don't know that.
"Obviously, he is going to be sorely missed, not just on the playing side of things but because he is the skipper of the side.
"But we've got Andy Tretton available and he's a possibility for tomorrow. We also have young Tom Smith. Fortunately, it's the one area of the side where we have a bit of strength in depth."
Looking forward to tomorrow's game with Crawley Town, Turner wants his side to get over the defeat at Hucknall.
"I don't think the Hucknall match will be too difficult to get out of the system. What we've got now is the opportunity to finish in the play-offs and we are more than capable of making it.
"But we've got a tough programme of 11 games in 36 days and it's a big challenge. If we got through the FA Trophy tie, it would have been 13 in 36 days.
"So the result on Tuesday does ease the burden in terms of fixture congestion but it's not to say we didn't try to win because we did.
"Crawley have done extremely well. We went down there earlier this season and should have won but they have gone on to have a good season. It won't be easy because they are a very, very hard-working side."
