West Ham full-back Ryan Fredericks has been ruled out until February with a hamstring strain.
The 27-year-old came off injured just before half-time in the Hammers' 2-0 FA Cup third-round win at Gillingham on Sunday evening, with opening goalscorer Pablo Zabaleta replacing him.
A scan has revealed a small amount of damage to the muscle in Fredericks' right leg and he has already begun his recovery work.
West Ham's head of medical, Richard Collinge, said: "Ryan injured his hamstring while chasing back late in the first half and was assessed immediately before undergoing a scan.
"He will now begin a period of rehabilitation and recovery, with the plan being to return to action before the end of February."
