Top Rank's CEO Bob Arum, who co-promotes WBC heavyweight champion Tyson Fury, says his boxer is not mentally affected by the numerous postponements to his ring return and the trilogy fight with Deontay Wilder.

Fury has been inactive since his February 2020 rematch with Wilder. He stopped Wilder in seven rounds to capture the WBC belt.

Fury was in serious talks to fight unified champion Anthony Joshua in Saudi Arabia - but the fight fell through when an arbitrator ordered Fury to honor a rematch clause due to Deontay Wilder.

They were initially scheduled to fight on July 24th at the T-Mobile Arena in Las Vegas.

The fight was pushed back to October 9 - after Fury tested positive for COVID-19.

"I'm not a psychiatrist but I spent considerable time with Fury after the arbitrator's decision then after his diagnosis," Arum told Sky Sports.

"It seemed to me he wasn't affected by anything. Tyson had a great mentality and none of these issues have any affect. Is he fooling me? Fooling himself? I don't think so. None of this has affected him adversely."

Arum was very disappointed with Fury testing positive and explains that there was a lot of negligence to go around.

"It was negligence on all of ours parts - Top Rank's and Tyson's. It started out with a nice, relatively small group, of sparring partners in our gym," Arum said.

"Before anybody realized the sparring partners were bringing in friends and [Fury's trainer] Sugarhill Steward had other fighters that he was training. Nobody was testing. It was going on the way we used to do it, before COVID. That was irresponsible on all of our parts.

"Tyson had a relatively mild case but had heavy breathing and congestion. There was no choice but to postpone it. We are hoping the bans on travel will be lifted and we will get some Brits over for the fight. They bring such a vibe to an arena!"
