Pierre Kalulu was not called up to the national team and was able to train regularly at Milanello until recently.
In one of the training sessions at the AC Milan sports centre, the French defender unfortunately suffered a muscular injury and now his presence in Saturday's derby against Inter is in serious doubt.
As reported this morning by the Italy-based newspaper Tuttosport, Pierre Kalulu has already started the recovery sessions, and his situation will be closely monitored until the eve of the Milan derby.
