Manchester City are sweating over the fitness of star man Kevin De Bruyne after the Belgian was taken from the field on a stretcher on New Year's Eve.
The injury occurred late on in City's surprise 0-0 draw at Selhurst Park, when Palace's Jason Puncheon put in a horror tackle on the midfielder.
Both players were left crumpled in a heap on the south London turf, before two stretchers took them off the field almost side-by-side.
After the game, De Bruyne was seen hobbling down the touchline, helped by members of the medical staff, in a minor boost for the league leaders.
