Sheffield Wednesday striker Will Keane could make a surprise comeback tomorrow.
The striker – on loan from Manchester United – limped out of last weekend’s draw with Brighton at half-time.
Owls head coach Stuart Gray revealed afterwards he feared the striker had suffered “knee ligament damage”.
But a scan showed just severe bruising and Keane has returned to training and could feature against promotion-chasing Derby County tomorrow as Wednesday look to end a six-game winless run.
Gray said: “Will is fully fit and available for selection on Saturday.
“He left after the Brighton game with a brace on his knee, but thankfully it was just bruising.
“He trained on Tuesday and has been fine so he is fine for Derby.”
Wednesday will be without captain Glenn Loovens, who is due to have a metal pin inserted into his fractured ankle in an operation which will rule him out for eight weeks.
“He’s going to have surgery,” said Gray. “They are going to pin it, which is bad news for Glenn and us.
“We are looking at a six-to eight-week period off. But these things happen in football. It’s part and parcel of the game. It’s disappointing for us, but we have to get on with it.”
Midfielder Jose Semedo also came off against Brighton with an ankle injury and is a doubt for the Derby trip. Semedo is also suffering with a toe infection.
Gray added: “Jose Semedo is touch and go. He’s wearing a boot which is taking the pressure off his ankle. We can’t seem to get the swelling down. He’s on a course of antiobiotics so he will be touch and go for Saturday.
“It’s disappointing for Jose because he is a big loss for us. For him to not be able to carry on until half-time, we know he’s got a problem.”
Charlton could call upon former Burnley and Bolton midfielder Chris Eagles to face Wigan away tonight after yesterday agreeing a short-term deal until the end of the season.
Speaking to the Addicks’ official website, the 29-year-old said: “I’ve had a great feeling about being here, it’s a massive club.
“I’m over the moon to be here and as soon as I knew they wanted to sign me it didn’t matter what they offered me, I just wanted to be here.”
