Boxing star Gervonta "Tank" Davis says he wants an MMA fight with UFC champ T.J. Dillashaw -- and now T.J.'s responding ... "Bring It!"
Tank has been talking about getting into the Octagon for a while -- previously telling TMZ Sports he truly believes he has the talent, athleticism and skill to compete in MMA.
And, after he watched T.J. beat up Cody Garbrandt at UFC 227 over the weekend, he tweeted out a challenge to the bantamweight champ.
