Check Out Derrick Lewis Beating Up A Boxer In The Gym

‘The Black Beast’ Derrick Lewis is not someone you want to be talking trash too as this loud-mouthed boxer found out to his detriment when he told the UFC star he could knock him out.

Needless to say the heavy-handed Lewis didn’t take too kindly to that and proceeded to give the boxer a brutal one-sided beatdown that was caught on camera and posted up by the man himself.
