Oxford boss Chris Wilder is optimistic that utility man Andy Whing could return before the end of the season.
Whing was injured in the FA Cup draw with Accrington and there were fears he could miss the rest of the season.
But Wilder told BBC Radio Oxford: "Whingy (ankle and knee) might not be as bad as first thought, hopefully it won't be that he's out for the season."
The U's boss added that he had no news on forward Jon-Paul Pittman's shoulder injury sustained in the same match.
"We're still waiting for the specialist to come back to us [about Pittman]," Wilder added.
It is the latest injury blow for the Oxford boss, who has seen his squad disrupted by injury throughout the season.
They already have top scorer Tom Craddock and fellow striker Deane Smalley out injured.
"They are all good players who we now can't select," added Wilder.
"If anyone looks at a season, they say you need the bounce of a ball, to stay clear of injuries and players producing their best form.
"We've not been able to do that one of those three - stay clear of injuries."
