Mark Noble hobbled off in the 51st minute to be replaced Matt Jarvis.
Earlier in the match Noble was fouled an flattened by Naismith who himself was stretchered off later in the game.
Morgan Amalfitano seemed also to take a battering especially from a bad foul from McCartney which could easily have seen the Everton player sent off.
Amalfitano was also limping during the game and was subbed on 82 minutes to be replaced by Ricardo Vaz Te, hopefully as a precaution.
The latest injury scares come on the back of injuries to Valencia, Sakho, Downing, Song and Kouyate all of which were declared unfit to play today.
