The Ivory Coast international lasted just 19 minutes of the crucial game at the top of the table before being forced off with the problem, with Javi Garcia coming on to replace him.
Manuel Pellegrini's men had another injury concern prior to the game with captain Vincent Kompany a doubt after picking up a knock in training and only being cleared to play after coming through the warm-up unscathed.

The Reds went into the game four points ahead of Manchester City, with Pellegrini's men having played two games less than their title rivals.
