Bolton Wanderers manager Owen Coyle has confirmed that midfielder Stuart Holden will be out of action for the next six months.
The American international will undergo a routine follow-up procedure on a knee injury that he sustained in last season's match away at Manchester United.
"Our prime concern has always been Stuart's welfare and his long-term health and fitness," Coyle told the club's official website.
"It was looking likely that the operation could be scheduled for next summer, but after follow-up consultations with the specialists we have brought the date forward."
Holden's one appearance this campaign came in the Carling Cup against Aston Villa last week.
