The incident at Betis' Manuel Ruiz de Lopera stadium happened soon after Sevilla had taken a 56th-minute lead through former Tottenham and West Ham striker Frederic Kanoute.

The Sevilla players immediately left the pitch, causing the game to be halted.

Ramos is said to have regained consciousness after being treated by medical staff.

The first leg, which had been played at Sevilla's stadium, had finished 0-0.
