HOUSTON -- If you think MMA social media is just a space for fans and media to spout off, well, think again.
Fighters might pretend they ignore what's being said online, but in reality, they're following along just as closely as everyone else.
That was rarely more obvious than Thursday, when it was clear the vast majority of the fighters at the UFC 192 media day at Toyota Center had heard about the beef between retired UFC Hall of Famer B.J. Penn and Nik Lentz.
On Wednesday, Penn, the retired UFC Hall of Famer and former two-weight-class champ, teed off on Lentz on UFC Tonight and offered to come out of retirement and fight him.
