Sevilla midfielder Joan Jordan was hit on the head by a long object thrown from the crowd at the Benito Villamarin
Real Betis reached the Copa del Rey quarter-finals after coming from behind to beat Sevilla in a game that started on Saturday and finished on Sunday.
The fixture was suspended in the 39th minute on Saturday after Sevilla's Joan Jordan was struck by an object thrown from the crowd.
It came just as Betis celebrated Nabil Fekir's equaliser after Papu Gomez had given Sevilla the lead.
The match resumed on Sunday and Sergio Canales scored a late winner.

Jordan had received treatment on the field after being struck on the head by the object, but got back to his feet and did not appear seriously hurt.
Play was halted for around 10 minutes before referee Ricard de Burgos decided to abandon the game.
Sunday's game was played with none of the 55,000 fans that had been at the Benito Villamarin for the game on Saturday.
