Former WCW wrestler Silver King died after collapsing in the ring during a show in London. The 51-year-old had been performing at the Roundhouse in Camden on Saturday evening.

Organisers of the Lucha Libre show confirmed his death as tributes from Black and others poured in for the Mexican, whose real name was Cesar Barron. He is said to have suffered a heart attack in the ring.

Silver King’s co-performers did not initially realise there was a problem after he collapsed following a kick to the side of his body while facing former WWE star Juventud “The Juice” Guerrera.

He was turned over and counted out but when he failed to recover, a team of medics rushed on stage, the newspaper said. Fans chanted “Silver, Silver” before the audience was told there would be a short break, and the venue was cleared out shortly afterwards, it was reported.
