Mike Jackson may have defeated CM Punk in an MMA fight, but Daniel Bryan says he could beat the inexperienced grappler on the ground if WWE were to let him fight in UFC. 

During a recent Instagram live session with Brie Bella, Daniel made a quick appearance and instead of taking fan questions, he asked: "Did they just ask me if I could beat Mike Jackson in a fight?"

"I could beat him on the ground, for sure ... I think," he quickly answered.

Nikki Bella is then heard in the background saying "prove it" and Daniel replies, "If WWE were to let me fight in the UFC, then maybe."

The former WWE champ sounds like he's kidding, but he could be more serious than you'd think. Daniel trained in MMA during his time away from wrestling and former UFC fighter Benson Henderson once said Bryan was very impressive while mixing it up at his gym.

Mike Jackson responded to Bryan in a statement to Fan Sided, saying: "Look Daniel Bryan; I will do you worse than I did your man Punk because I will have no reservations in punching this guy in the face 100-percent. And at will.” 

He also tweeted, "Hey, , don’t let your mouth write a check your ass can’t cash. You don’t want to get potatoed like your mans did at ."
