Olympique Lyon owner John Textor admits Fabio Grosso cannot speak after bus window was smashed by Olympique Marseille ultras yesterday.
The window exploded in front of Grosso and left him with cuts across his face.
The match was called off due to the ultras attack and Crystal Palace director Textor revealed later: “Fabio had received medical advice, he cannot hold a conversation, he is not well, he was hit by stones and shards of glass.
"We are angry, very angry, everyone wanted to play.
"But no one was ready for that, but we wanted to play, we are angry, our captain was strong in the locker room."
