IBF world heavyweight champion Anthony Joshua said patience would be the key to preserving his perfect knockout run after weighing in almost a stone heavier than American challenger Eric Molina for their showdown.
The 27-year-old British boxer showed off an impressive physique when tipping the scales at 17 stone 11 pounds (113kg) - six pounds heavier than for his last fight - as he looks to make it 18 knockout wins from 18 professional bouts.
"People love the thud of punches and there will be a knockout," said Joshua who won Olympic gold at the London 2012 Games. "Almost everybody is saying I'm the favourite but I don't see it like that. I take him as a real challenger. I've got to stay calm, wait for him to fatigue and then unload," added Joshua amid increasing expectations that he is poised to become the first billionaire boxer through his endeavour in the ring and endorsements outside of it.
Molina, 34, who has suffered three defeats in 28 bouts, weighed in at 16 stone 13 pounds.
The Texan is widely expected to be merely a stepping stone for Joshua, with a match against former heavyweight king Wladimir Klitschko pencilled in for next April.
Dillian Whyte and Dereck Chisora weighed in separately for their heavyweight grudge match after Chisora was fined £25,000 by the British Boxing Board of Control for throwing a table at a news conference.
