Tyson wasn't very active before the Usyk mega-fight. In 2023, he only fought Francis Ngannou, technically a win, but not one to be proud of. He got knocked down by a guy with little to none boxing experience, ho later got ran over by Anthony Joshua.
So this must feel like a 2nd loss in a row for him, which is usually a massive blow to the confidence, especially for the fighters who have been previously undefeated.
But who knows, maybe this will actually work nicely for his motivation. In the past, he mentioned he was lacking motivation for regular fights, but now, everything's on the line for him.
