Eddie Hearn, promoter for heavyweight contender Dillian Whyte, is more concerned about his boxer's mental state when he enters the ring for his upcoming rematch with Alexander Povetkin on November 21.

Last month at Matchroom's Fight Camp in Brentwood, Whyte was knocked out cold in the fifth round by Povetkin.

Povetkin had been down twice in the prior round, before clipping Whyte cold with a perfect uppercut in the fifth,

Whyte exercised an immediate rematch clause, with the second fight scheduled to take place on November 21.

Some observers have expressed worry about Whyte's physical condition, with the rematch taking place so soon after he suffered a vicious knockout.

But Hearn is not worried about Whyte's physical state. He's more focused on the mental aspect. The outcome of the first contest could be hanging in the back of Whyte's mind while he's in the  rematch.

“There are two ways to look at it; Dillian controlled the fight and was moments from winning until a one-in-a-million punch stunned him and the chances of that happening again in the rematch are very small," Hearn told The Sun.

“Or you can say that Povetkin took two of Dillian’s best shots, got off the floor twice and stopped him with the only real punch he connected with. It wasn’t a 12-round war or a prolonged beating so physically Dillian should be fine but the rematch is more about the psychological side.

“Dillian demanded the rematch straight away, no hesitation, because he believes it was just a split second mistake that he can correct. But Povetkin also snapped up the rematch because he now thinks he has the beating of Dillian and can pop back over to double his money with another easy night’s work. A knockout like that you can physically recover from reasonably quickly. But mentally it can leave a mark on fighters and we will find out on November 21.”
