"The Rock" Johnson addressed Usyk, asking him not to break his jaw

"Don't break my jaw, champ. I'm honored that newly crowned absolute world heavyweight champion Oleksandr Usyk has joined our cast of "The Smashing Machine." Usyk will play the role of Igor Vovchanchyn, a real-life Ukrainian MMA legend who has had legendary fights in the era of extreme bare-knuckle martial arts and one historic fight against the Smashing Machine himself, Mark Kerr. "I have the utmost respect for Oleksandr Usyk and will be honored to share the ring with him when he breaks my jaw next week," "The Rock" wrote on his Instagram.
