Inter Milan have suffered a double injury blow as both Diego Forlan and Coutinho have been ruled out with hamstring injuries.
Tests at the Italian club on Thursday confirmed the damage to his left leg.
Meanwhile young Brazilian forward Coutinho also hurt his hamstring after slipping during training in the morning, although his injury is not as bad as Forlan's.
It's bad news for Inter ahead of Saturday's trip to Catania as they are already missing Thiago Motta with both goalkeeper Julio Cesar and playmaker Wesley Sneijder rated as doubtful while Andrea Ranocchia and Joel Obi are suspended.
