Bolton midfielder Stuart Holden faces at least the next six weeks on the sidelines after fracturing his right fibula.
Holden, who joined Wanderers in January on a short-term deal until the end of the season, sustained the injury during United States' 2-1 friendly defeat to Holland on Wednesday night.
Holden had started Bolton's last two matches, impressing manager Owen Coyle, who on Thursday confirmed the 22-year-old's contract has been extended through to the end of next season.
