USA international Stuart Holden is unlikely to play for Bolton Wanderers again until mid-April after picking up an injury while on international duty.
The 24-year-old could be sidelined for up to six weeks after suffering a fracture in his leg after being tackled by Nigel de Jong during the United States' friendly against Holland in Amsterdam on Wednesday evening.
Wanderers manager Owen Coyle said:"It's disappointing for Stuart because he's come into the team and done ever so well.
"He's a very good player, an international player, and he's shown a real hunger and desire to do well for our football club.
"In both games against Tottenham Hotspur and Wolves everybody saw the quality that he has so it's a blow, but the most important thing is that he returns bigger and better."
Holden was taken to hospital immediately where the extent of the injury was diagnosed.
He moved to the Reebok Stadium in January, initially on a short-term deal, but Coyle has since said the contract has been extended until the end of the season.
