Suarez hero and villain

Luis Suarez scored and was sent off as holders Barcelona reached a fourth successive King's Cup final after drawing 1-1 with a resilient Atletico Madrid in an action-packed semifinal second leg on Tuesday.

Suarez was one of three players dismissed and will now miss the final after Barcelona edged through 3-2 on aggregate.

The Uruguayan tapped in from close range in the 43rd minute after an inspired run and shot from Lionel Messi to deliver a sucker punch to Atletico, who had dominated the first half at the Nou Camp but failed to take their chances.

Kevin Gameiro blazed a penalty over the bar with 10 minutes remaining but the French striker still made for a tense finale by tapping in an Antoine Griezmann cross moments later.

Barca defender Sergi Roberto will also be suspended for the final after being sent off for a second booking in the second half and Atletico winger Yannick Carrasco was dismissed as well for a second yellow card.

Suarez was then sent off in the 90th minute for an elbow on Atletico midfielder Koke.

Atletico had five minutes of stoppage time to snatch a winner and force extra time, but Barca withstood the pressure.
