Brock Lesnar has defeated CM Punk in a brutal encounter at Summerslam, which is taking place at the Staples Center in Los Angeles.
Lesnar used his considerable size advantage to dominate the former WWE champion during the opening half of their "No Disqualification" encounter.
Punk battled back against the former UFC heavyweight champion, but he failed to make Lesnar tap with the triangle choke.
However, Punk looked to have the match won on two occasions before he was denied by interference from Paul Heyman.
That allowed Lesnar to regain control and after delivering an F-5 onto a steel chair, he successfully got the pinfall victory.
