Jason "Mayhem" Miller meets Aaron Simpson at UFC 132

On Friday, Jason "Mayhem" Miller (24-7 MMA, 0-1 UFC) announced he was returning to the Ultimate Fighting Championship.

On Saturday, UFC brass announced he's already lined up to fight.

UFC officials today announced Miller will meet wrestling standout Aaron Simpson at July's "UFC 132: Cruz vs. Faber II" event.

Miller's return comes six years after a lone appearance at welterweight in which he was dominated by Georges St-Pierre. "Mayhem" now returns to the UFC as a thoroughly experienced middleweight. Miller is 12-3 with one no contest since his ill-fated trip to the octagon and lost a unanimous decision to Jake Shields for the vacant Strikeforce middleweight belt in November 2009.

Outside of the cage, Miller has kept busy as the host of MTV's popular reality show "Bully Beatdown," which completed its third season this past December. It's unknown whether a fourth season is in the works.

UFC 132, which is the UFC's Independence Day-weekend show, takes place July 2 at the MGM Grand Garden Arena in Las Vegas.

The night's main card, including a championship headliner between bantamweight titleholder Dominick Cruz and Urijah Faber, airs live on pay-per-view. MMA Junkie
