The long-rumored Aaron Simpson (11-3) vs. Jon Fitch (23-4-1) welterweight fight appears to have a date.

During a Q&A session, Simpson said he'll make his welterweight debut in July against Fitch.

Simpson, a two-time NCAA Division I All-American wrestler, fought once for the WEC and eight times for the UFC as a middleweight, and he posted a 7-1 record in the process. But following a close split-decision defeated to Ronny Markes at UFC on FUEL TV 1 in February, the 37-year-old announced his intentions of dropping a weight class.

Fitch, meanwhile, fights for the first time since his disappointing 14-second knockout loss to now-top contender Johny Hendricks in December. Prior to the defeat, the American Kickboxing Academy member and former Purdue University wrestling captain was on a 5-1-1 run that included wins over the likes of Paulo Thiago, Mike Pierce and Thiago Alves.

UFC on FUEL TV 4 takes place July 11 at HP Pavilion in San Jose, Calif.

UFC fighter Nick Diaz no-showed a scheduled World Jiu-Jitsu Expo superfight with Braulio Estima on Saturday in Long Beach, Calif.

Diaz's absence understandably left fans and Estima steamed.

Diaz, who reportedly was going to donate his purse to charity, initially offered no explanation for skipping the event, which was sold online as a $9.95 pay-per-view.

The event included five other jiu-jitsu bouts – Kyra Gracie outpointed Strikeforce's Alexis Davis, for example – but world champion Estima was left standing on the mat as he awaited Diaz, who never showed for the featured attraction. Event organizer Renzo Gracie later announced the superfight had been scratched because Diaz didn't arrive.

"For Nick, I gave up a lot of things to make this happen," Estima said afterward. "I came here to fight. You said that you were going to gave this all to charity, make all these speeches and stuff. I'm here now. You let everyone down. You let me down.

"I think this is very disrespectful. I didn't expect this from you."

Estima, who previously hinted at a possible move to MMA, said he would fight Diaz in the cage, assuming he shows up.

"I will fight him any time, and I'll make sure I'm there," he said.

While both camps argued about the other making weight, Estima assured reporters and fans he made 180 pounds on Saturday. He said no one saw Diaz make weight.

Diaz is currently suspended after failing a post-fight drug test in February following a UFC 143 loss to Carlos Condit. He cost himself a title shot back in October when he no-showed a pair of pre-event press conferences for a scheduled title shot with welterweight champion Georges St-Pierre.

"He has a problem," Estima said. "He has a social issue. This isn't his first time doing this.

"This isn't letting me down. This is letting the kids down. This is like out of order."

James Wilks, a British welterweight who won season nine of the UFC's Ultimate Fighter just three years ago, has elected to retire after seeing his career set back by a slew of injuries.

The 34-year-old made the announcement on Twitter over the weekend.

Wilks, who is from Leicestershire, England, represented his home country in a 2009 season with international flavor, dubbed TUF: United States vs. United Kingdom.

During the competition, he beat recent UFC 145 co-main event fighter Che Mills, Frank Lester twice and then tapped out DeMarques Johnson with a rear naked choke in the final to win the trophy.

Memorably during the season, Johnson offered Lester money to knock out Wilks' teeth, and as it turned out, Wilks knocked out four of Lester's teeth with a knee from the clinch.

He went 2-2 in four official trips in the octagon. Aside from his victory over Johnson -- the final is the only TUF bout to be sanctioned as an "official" fight -- he won a UFC 115 bout against Peter Sobotta, but lost matches against Matt Brown and Claude Patrick.

Wilks' last time in the cage was well over one year ago, when he fell to Patrick at UFC 120 in October 2010.

He was supposed to fight against Amir Sadollah last March but was forced out due to a serious knee injury.

Wilks retires with a 7-4 career record.

He has said he will spend his future concentrating on his gym, Lightning MMA in Laguna Hills, California.
