Maybe Luke Rockhold wasn’t sure how Vitor Belfort prefers to stand during pre-fight staredowns.

Well, earlier this week, the former Strikeforce champion found out first-hand just what Belfort does – literally.

As Belfort locked eyes with Rockhold, he proceeded to put his right fist right in his face. While Rockhold didn’t back down or say anything at the time, he took to Twitter to express how fired up that made him.

“Press conference (Thursday). Can’t stand fist to face (expletive), he will get his, I promise!” Rockhold wrote, who has called out Belfort for his use of TRT.

The two will meet tonight at UFC on FX 8 from Brazil, with “The Phenom” holding the obvious home-Octagon advantage.
