The 33-year-old British fighter hasn't boxed since beating Wilder back in February 2020 but Arum suggested he is in superb shape for the trilogy bout, which will be held in Las Vegas on October 9.
Arum told Boxing Scene: "I talked to him [Tuesday]. He was shouting how great he’s doing, how he’s killing sparring partners. He arrives in Las Vegas on Saturday, this Saturday. He’ll take Sunday off and then he’ll resume training at the Top Rank Gym on Monday. He’s been training twice a day in England. And ‘Sugar Hill’ is over there with him."
The bout had been supposed to take place in July but was delayed after Fury and several members of his support team contracted coronavirus but Arum is confident that his fighter has recovered from the disease.
Arum explained: "I went to see him the day after he got diagnosed with COVID [early in July]. At that point, he was drinking a lot of water and having trouble, not breathing, but his lungs were very congested. But he was in, I guess, such good shape that by the end of the week, he was OK. He was troubled that he wouldn’t be OK in that period of time, when I talked to him [two weeks before he was supposed to box Wilder]. But in fact, he was. And he was also concerned because eight people in his camp had come down with COVID, including his chef. That’s why he asked for the postponement. But he’s been doing great."
