Wilder has not ruled out that the fight with Zhilei will be his last for him

It was revealed the day before that the American and the Chinese will cross gloves on June 1 as part of an evening of boxing in Riyadh, Saudi Arabia.

"I respect Zhang, he's a great fighter, but it's my time. We'll find out on fight night if I'm still capable of winning or not. I see this as my last chance.

I'm not playing around this time. I feel like I have nothing to lose, only to win, and I mean business. I feel the desire is coming back to me. You know what I mean," Wilder said at the press conference.
