Barcelona, Deportivo and Getafe are through to the semi-finals of the Copa del Rey, while Sevilla's clash was abandoned.
Sevilla's derby clash at Real Betis had to be abandoned on Wednesday after shameful scenes which saw visiting coach Juande Ramos taken to hospital.
With the second leg evenly poised after a goalless draw in the opening game, trouble erupted after Freddie Kanoute gave the visitors the lead 12 minutes into the second half - a goal that sparked violence from the Betis fans with one launching a bottle that struck Ramos on the head.
The Sevilla coach collapsed following the impact (pictured) and was stretchered from the field having lost consciousness, but was awake before boarding an ambulance.
It is not yet clear whether the remaining time of the match will played at a later date, or whether Sevilla will be awarded the tie.
Barcelona exacted revenge on Real Zaragoza after advancing on away goals following a 2-1 win.
The Catalan giants were stunned at Camp Nou, but a superb first-half showing helped them seal a semi-final place.
Xavi opened the scoring with Andres Iniesta adding a second within the opening 26 minutes of the game.
Andres D'Alessandro was given his marching orders in the second half, but it did not quash Zaragoza's commitment.
Gerard Pique managed to bring the sides level on aggregate for the 10 men, although they failed to net again and crashed out.
Deportivo La Coruna booked their place in the semi-finals of the Copa del Rey with a comfortable 5-2 aggregate win over Segunda Liga outfit Valladolid.
The Riazor outfit brought a commanding 4-1 lead into the second leg and padded their advantage when Luis Kasmirski Filipe netted.
Things turned sour when Fabricio Coloccini was given his marching orders, but the 10 men held out comfortably enough.
Vladimir Manchev did pull one back in the closing stages although Victor's dismissal ensured both sides finished a man light.
Osasuna secured a 1-0 win over Getafe, but it was no good enough to overturn a 3-0 first leg deficit.
Bernardo Romeo opened the scoring just 15 minutes into the contest, although it proved the only goal of the game as Getafe cruised home.
