Chelsea boss Frank Lampard says Mason Mount could make their clash on Sunday against Liverpool.
Mount, who has scored three goals in Chelsea's opening five league games, was forced off early in Tuesday's Champions League defeat to Valencia.
"He's got a chance," Lampard said. "The image of the tackle afterwards made it look really bad, but hopefully it's not so bad.
"We're trying to get him moving today and it's one I'll have to call just before the game with another 24 hours in the bank.
"The good thing with Mason is his attitude is so good that he'll give everything to get out there and play for this club, particularly in a game of this size."
