Joe Joyce secured the biggest victory of his professional career by stopping former WBC heavyweight champion Bermane Stiverne in six rounds.
The 33-year-old, in his eighth fight, knocked down Stiverne with a big right hand in the third before forcing referee Howard Foster to intervene after two minutes and 20 seconds of the sixth amid another sustained attack.
'Big respect to Bermane Stiverne, he's very tough and stuck in there but I guess I was just too much,' said Joyce.
'It was about being patient as he's such a tough guy he took all those shots. There are big things to come.'
Wales' Lee Selby survived cuts over both eyes to earn a unanimous points decision over Omar Douglas on his move up to the lightweight division.
The 32-year-old had not fought since last May when he lost his IBF featherweight title to Josh Warrington.
