UFC light heavyweight champ Jon Jones (18-1) recently offered up some rough remarks aimed at unbeaten heavyweight Daniel Cormier where he questioned the Olympian’s work ethic based on his physique and made fun of Cormier’s smaller fanbase. Jones’ insults came after a line of questioning involving Cormier’s plan to slim down to 205 pounds and challenge for the belt, a move “DC” plans to make after his October outing against Roy Nelson at UFC 166. According to Jones, he’d grown sick of talking about Cormier and felt the need to unleash some of his frustration. However, it appears his plan may have backfired.

Cormier caught wind of Jones’ comments and offered up a salty response on last night’s Fuel TV coverage of UFC 163.

“When I heard his quote, it’s like a 16-year old girl,” stated Cormier. “Jon Jones, grow up bud. We’re going to fight regardless of how you feel. And when we do and I’m cutting the line and you might as well pull guard because I’m taking you down.”

Of course, the 12-0 Cormier will have to get by Nelson for the match-up to materialize, while Jones will also have to emerge with his hand raised in relation to a September 21 title-defense against Alexander Gustafsson.
