Bolton Wanderers midfielder Darren Pratley has been ruled out of action for at least six weeks with a torn hamstring.
The 29-year-old suffered the injury during his side's 2-2 draw with Wolverhampton Wanderers on Saturday.
Pratley has scored five goals in 27 games for the Trotters so far this season.
Bolton are back in action tomorrow night when they host Liverpool in an FA Cup fourth-round replay.
