West Ham defender Winston Reid has been ruled out for the rest of the season because of injury.
Reid, 29, was taken off on a stretcher with an oxygen mask over his face after being knocked unconscious and twisting a knee in Saturday’s defeat by Swansea.
Full-back Sam Byram, 24, could also miss the rest of the campaign after injuring his ankle in the 4-1 loss.
David Moyes’ side are currently 14th in the Premier League, three points above the relegation places.
Defenders Angelo Ogbonna and James Collins, who missed the Swansea game through illness and a tight hamstring respectively, should be available for the game against Burnley at the London Stadium on Saturday.
