On yesterday afternoon's taping of "Undisputed" on Fox Sports 1, Clippers guard Austin Rivers spoke about playing for his father Doc and how one of his former teammates, Glen "Big Baby" Davis, has been so critical of his dad since leaving the team.

Austin went on to say Big Baby was constantly out of shape and couldn't remember plays, among other things. Check out a clip from the show below.

Austin Rivers later made an appearance on "The Herd" with Colin Cowherd and continued the discussion. 

Shortly thereafter, Big Baby took to instagram to address Austin's comments [from Hawaii], claiming that Austin only has a job in the NBA because of who his father is.

"I seen you at practice. You didn’t give a (expletive), thinking you all that wearing them tight ass pants and you know, your father gave you all that money, so you can go wear those tight ass pants, but keep your (expletive) mouth closed, man. Shut up, man. You’re a (expletive) bum who’s been given the world. Shut up and just stay under your father.”

Check out Big Baby's hilarious rant below.
