West Ham United midfielder Pedro Obiang looks set to miss the rest of the season with an ankle injury.
The Spaniard, who has emerged as one of the Hammers' most consistent performers this term, picked up the problem in the 3-2 defeat at home to Leicester.
Obiang, 24, appeared to roll his ankle during the second half at the London Stadium and was carried off on a stretcher.
West Ham had already lost defender Winston Reid to an adductor injury in the first half, and he is due to undergo a scan later this week and the club fear their New Zealand international could face around six weeks on the sidelines.
In a triple injury blow for manager Slaven Bilic, winger Michail Antonio suffered a hamstring problem which has forced him to withdraw from the England squad to face Germany and Lithuania.
Jack Sullivan, the son of joint-owner David Sullivan, tweeted:

West Ham travel to Hull after the international break and hope to welcome back captain Mark Noble, who missed the Leicester game with a dead leg and was given an extended break by Bilic.
