Bob Arum is encouraged about Tyson Fury’s health after speaking to the heavyweight titleholder.

Arum told BoxingScene.com that Fury, stricken with the coronavirus, sounded better on a phone call Monday than he did when the fighter’s co-promoter visited him Thursday in Las Vegas.

Fury’s title defense against Deontay Wilder, scheduled for July 24 at T-Mobile Arena in Las Vegas, was postponed after he tested positive for the virus. Organizers are targeting Oct. 9 at T-Mobile for the fight.

“His spirits were OK,” Arum told the outlet. “He had congestion in his chest [Thursday]. But as of [Monday] morning, he seems much better.”

Fury reportedly had received the first Moderna vaccination but not the second. Arum said he has agreed to get vaccinated before meeting Wilder for a third time.

“He’s fine with it,” Arum said. “He got vaccinated in Miami. He got the first shot. And then he said he didn’t want to get the second shot because he didn’t want to get sick [from the vaccination] so close to the fight. So he got COVID instead.”

Fury, who lives in Las Vegas, plans to return to his home country of England for a few weeks and then return to the U.S. to resume training. It’s not clear how he will be able travel with COVID-19.
