Wigan Athletic have confirmed midfielder Ben Watson sustained a double leg break following an accidental collision during the club's 2-0 Sky Bet Championship victory over Barnsley on Tuesday.
The incident came in the 15th minute of the match at the DW Stadium when Watson went in for a 50-50 tackle with Barnsley midfielder Martin Woods.
Watson, who scored a dramatic late winner in the club's FA Cup final victory over Manchester City last season, was carried off the field on a stretcher and immediately taken to Wigan Infirmary.
The 28-year-old suffered a double fracture to the fibula and tibia bone his right leg and will undergo surgery as soon as possible.
It is the same leg which he broke in a match at Liverpool in November 2012, but not in the same place and Wigan manager Uwe Rosler confirmed the injury is not considered career-threatening.
"Until everything was confirmed, we did not want to go on the record but we have now had time to make a good assessment," Rosler said.
"Ben will receive the best possible treatment and we will do everything to help him make a speedy recovery.
"He is a terrific professional, a fighter, and I am sure he will return from this latest setback like he did a year ago when he went on to experience the high of scoring the winning goal in the FA Cup Final at Wembley, and write himself into the heart of every Wigan Athletic supporter.
"To lose a player and a person of Ben's quality is a big blow to us but we will re-group and move on as a squad and keep trying to achieve our goals for the season, with the added incentive now of doing it for Ben."
