Wigan boss Roberto Martinez has confirmed midfielder Ben Watson suffered a broken leg during his side's 3-0 defeat at Liverpool.
Watson sustained the injury in a collision with Raheem Sterling in the first half of the game at Anfield.
The midfielder received lengthy treatment on the pitch before hobbling off and being replaced by David Jones.
Martinez has now confirmed Wigan's worst fears that Watson sustained a serious injury in the incident, but he excused Sterling of any blame.
"I haven't seen the challenge back, but I don't think any of the players were looking at each other," said Martinez.
"Both were looking at the ball - it's a real accident. It's a nasty collision."
The injury means Watson will be out of action for up to three months and is set to return in the New Year.
