UR Fight results: Chael Sonnen vs. Michael Bisping ends in draw, Roy Jones Jr. scores massive KO

PHOENIX -- Four years after their fight on FOX, retired middleweight Chael Sonnen and UFC contender Michael Bisping met once more in an exhibition grappling match Sunday night at UR Fight -- the smorgasbord online pay-per-view from UR Show which also featured MMA, pro wrestling, and the boxing return of Roy Jones Jr. at the Celebrity Theatre.

Sonnen and Bisping first clashed in early 2012 at UFC on FOX 2, with Sonnen claiming a narrow unanimous decision to secure a UFC title shot against Anderson Silva. The win never sat right with Bisping, however the Brit was unable to exact much vengeance at UR Fight. Bisping, weighing 212 pounds, worked to uneventful draw against Sonnen, who weighed in at 231 pounds.

The match was contested under Metamoris rules, making a submission the only way to secure a victory. Bisping and Sonnen spent much the first two rounds circling, hand fighting, and interacting with the crowd. At one point a "USA!" chant broke out, only to get shut down when Bisping pulled out his Union Jack mouthpiece. Sonnen finally secured the only takedown of the match with 45 seconds left in the final round, but was unable to do anything with it.

Afterwards, Bisping apologized to the fans for the slow performance, while Sonnen gave Bisping props for his recent decision victory over Silva.

"He's the No. 1 contender, bottom line. Let's get behind him and get him a world title fight," Sonnen said.

In the night's main event, boxing legend Roy Jones Jr. fought a contest-winning fan/pro MMA fighter, Vyron Phillips, and subsequently scored a massive, highlight-reel knockout.

Jones Jr., 47, played around for much for the first round, only throwing out a right hand at the end which staggered Phillips. He finished the job a few minutes later, flooring Phillips with a right hand counter at 2:30 of the second round.

The MMA portion of the main card was supposed to feature a battle of UFC Hall of Famers between Dan Severn and Ken Shamrock, but instead saw a trilogy match between MMA veterans Shannon Ritch and Mavrick Harvey after a flurry of late changes. And it didn't take long for the fight to devolve into bedlam.

An early Harvey bullrush sent Ritch flying outside of the ropes. The referee tried to regain order, but Harvey continued raining down punches with Ritch caught halfway in, halfway out of the ring. Once the fight was finally reset, Harvey charged again but ended up on the mat with Ritch sinking in a fight-ending rear-naked choke. The official time of the finish came at 1:32 of the first round.

Finally, in a match between pro wrestling legends, Rey Mysterio defeated Kurt Angle via pinfall with help from musical guest Riff Raff. And that, ladies and gentlemen, is perhaps the most bizarre sentence I've ever written on MMA Fighting.
