Fuse is lit for main event for jam-packed card in Brazil.
Hometown hero Vitor Belfort and promotional debutant Luke Rockhold made weight for the main event fight at UFC on FX 8 but the real talking point was what happened when both men stepped off the scales.
Talk has been high by both fighters ahead of their middleweight bout, with Rockhold chipping the veteran about his use of Testosterone Replacement Therapy and being predictable.
While from camp Belfort, the elder statesman of the Octagon said the old dog has learned a new trick or two just for the former Strikeforce champion.
After both men made the 186 pound limit at the Arena Jaragua in Jaragua do Sul, they immediately began their intense face-off.
After the final press-conference Rockhold made it clear he did not like Belfort putting a hand under his chin and made sure he knew about it at the weigh-in.
The young American closed the distance quickly before Belfort shoved his opponent causing UFC officials to quickly separate the two.
With the winner of the bout likely to become the number contender for the middleweight title, the sparks before the bout could be seen as legitimate competition, not simply showmanship to boost television ratings.
