Bob Arum believes that Deontay Wilder is the underdog going into his fight with Zhilei Zhang this weekend.
The two heavyweights are both coming off defeats, both to Joseph Parker.
Wilder is known as a fearsome puncher, and Zhang has a reputation for heavy hands too, and they are going to fight as the headline event for Queensberry vs. Matchroom in Riyadh on Saturday live on DAZN.
It is hard to say who will come out on top given their recent losses and their relatively advanced age - Wilder is 38 and Zhang is 41.
Speaking to Sky Sports, Arum believes that Wilder has fallen off of late, and backed the Chinese fighter to succeed.
"But I really believe that Zhang is gonna be too much for Wilder, I think Wilder has slipped a little bit,” he said.
"Zhang is an awfully good fighter, he's a rough, tough heavyweight, but we'll have to see what happens in that fight on Saturday."
