According to Marca, Barca club doctors have diagnosed Keita with a two centimetre tear in the semitendon muscle of his right leg. He will, therefore, be out for at least 15 days.
The Malian international was substituted at half-time, with his substititute, Pedro, going on to score the vital equalizer.
It is currently expected that Keita will be fit just in time for the African Nations Cup.
