GOALKEEPER David Forde dislocated a finger during Saturday's loss at Barnsley.
Forde suffered the injury making a brave save at the feet of Tykes striker Chris O'Grady but played on after treatment from physio Bobby Bacic.
The long-serving Lions stopper is expected to return to training later this week and should be available to face Brighton at the weekend.
Bacic told the club's official site: "David dislocated his little finger performing a save during the second-half.
"Luckily he managed to remain very calm and allow the finger to be relocated on the pitch, which is a very painful procedure.
"In a way it adds further insult to injury as it is just as painful as the original force needed to dislocate the finger in the first place."
