NFL's Kroy Biermann: I'd Try MMA If My Famous Wife Let Me

NFL linebacker Kroy Biermann says he'd be all the way down to try his hand in a real-life MMA fight ... if his famous wife, Kim Zolciak, would let him. So, we asked her!

Kroy was co-hosting the "TMZ Sports" show on FS1 Monday night when he told us he's a huge MMA fan -- who happens to have a wrestling background.

You gotta see what Kim says when we bring up the plan -- long story short, she shuts him down faster than Conor McGregor shut down Jose Aldo!

BONUS -- we also ask Kroy -- who happens to be a free agent -- where he wants to play next season and if Kim has a say in where he signs. Check out the clip!
