Streaking lightweight Melvin Guillard will get another chance to prove that he belongs in the upper echelon of the 155-pound division when he attempts to stuff the wrestling prowess of WEC import Shane Roller at UFC 132, which is tentatively scheduled to take place at the Mandalay Bay Events Center in Las Vegas, Nevada, on July 2, 2011.

The promotion today announced the bout on its official website.

Guillard, whose career was once as erratic as Charlie Sheen's sobriety, recently righted the ship with the help of renowned mixed martial arts trainer, Greg Jackson.

He hasn't lost a fight since the switch.

A dull decision win over Jeremy Stephens left many wondering whether he had adopted  "play-it-safe" approach, but the "The Young Assassin" squashed those misperceptions by putting his stamp all over Evan Dunham in the UFC Fight for the Troops 2 main event back in January.

The upset win, his fourth straight, over such a highly-touted prospect had Guillard calling for a title shot soon. He'll get the opportunity to prove he means it when he takes on the gritty three-time All-American wrestler on Fourth of July weekend.

Roller did his best Joe Warren impression at UFC Live on Versus 3, getting badly outworked by Thiago Tavares for six minutes before flooring the Brazilian with a wicked one-two combination that stopped the fight on a dime.

The Team Takedown standout is on a roll since a submission loss to the last man to hoist the WEC lightweight title, Anthony Pettis, winning five consecutive fights. Despite his rich wrestling pedigree, Roller knows how to finish fights, notching nine stoppages among his 10 career wins.

Guillard and Roller are both coming off of "Knockout of the Night" performances. Don't blink.

UFC 132, which was just referenced today for the first time by the promotion, does not have a main event in the works at this time. But if this match up is any indication, fans can once again expect fireworks in "Sin City" on Independence Day.
