Alexander Povetkin of Russia became the mandatory challenger for the WBA heavyweight belt after brutally knocking out David Price in the fifth round of an action-packed fight.
Povetkin had already floored Price with a big left hook in the third round when he sent the British boxer to the canvas with another powerful left that drew gasps from the crowd.
Price was a sitting target after being hit with a right jab from Povetkin, who becomes the WBA intercontinental champion. Povetkin, the 2004 Olympic champion, was WBA champion from 2011-13.
Price started his pro career with 15 straight wins but has now lost five times, four of the defeats coming against boxers who had served - or would go on to serve - doping bans.
The 38-year-old Povetkin twice tested positive for performance-enhancing drugs in a seven-month period in 2016. Either side of that, he has won eight straight fights, leaving the loss on points to Wladimir Klitschko in 2013 as his only defeat in 35 bouts.

The Northern Irishman still won easily with all three judges.
Parejo, of Venezuela, previously won four straight fights after losing the interim WBA title.

British lightweight Anthony Crolla could be in sight of another world title fight, but he made heavy work of his unanimous points win over unheralded Mexican Edson Ramirez in one of the big three bouts on the undercard.
Crolla fought with a cut near his right eye from the third round and blood covered his face for large parts of an uneventful fight.
A former WBA champion, Crolla could yet get another shot at that belt - maybe against fellow Brit Luke Campbell - as it could soon become vacant.
Jorge Linares, who beat Crolla in back-to-back fights in Manchester, owns the strap and is soon fighting Vasyl Lomachenko. Linares, a 32-year-old Venezuelan, is coming toward the end of his career.
