“The match has been abandoned after Joan Jordan was hit by an object thrown from the stands. We’ll provide you with further updates,” Sevilla wrote on Twitter.
Alejandro Gomez put Sevilla in front in the 35th minute, but the lead lasted four minutes before Fekir’s leveller.
Video replays showed that Jordan was struck from behind and collapsed to the ground holding his head, although reports said he was later able to stand while receiving medical attention.
The Spanish Football Federation (RFEF) announced that the game was suspended, adding: “The RFEF condemns any act of violence on the pitch.”
