UFC star Coby Covington challenges 50 Cent to a $ million fight saying, ‘When I hit you, you won’t get up!’ And the shocking part is that 50 is seriously considering it, according to sources close to the rapper. The challenge comes as a result of Coby’s recent defeat during a fight with Kamarau Usman at UFC 245. In true 50 fashion, he taunted the fighter, and this is the outcome.
