Charlton defender Jason Pearce will have a scan today to determine whether he has injured his knee again.
Pearce, 30, missed almost three months with a knee problem and made his league return against Blackburn last weekend.
But he landed awkwardly after kicking a ball in training on Tuesday.
Charlton boss Karl Robinson told News Shopper: “Pearcey might be injured again - his knee might be sore again.

“He just struck a ball and landed awkwardly. It won’t be that bad but he’s having a scan to see what it is.
“Every injury we've got, it’s been through something different, it’s not because of training or the pitches. All our injuries have been to some of our main players.”
Pearce could join Tariqe Fosu, Ahmed Kashi, Patrick Bauer, Ricky Holmes, Jake Forster-Caskey and Lewis Page in the treatment room if his injury is serious.
