Swansea City defender Marcos Painter will be out for at least three weeks with a torn hamstring.
Painter sustained the injury during Monday's Johnstone's Paint Trophy second leg against MK Dons and was forced off after just 17 minutes.
"The injury is largely down to the huge number of games we have had to play in recent weeks," Swansea physio Richie Evans told the club's official website.
"There are some tired bodies in the squad."
Painter has tallied 25 League One starts so far this campaign.
