“Karo Parisyan has f***** over the UFC, the fans and his opponent again. He will not be fighting Saturday or ever again in the UFC,” wrote White. “Pulled out of the fight the day before weigh-ins again with a laundry list of excuses. Let the press ask Karo why. Let him explain.“

Parisyan (18-5), a longtime contender at 170-pounds, was to return to the UFC after serving a nine-month suspension for testing positive for banned painkillers after a January win over Dong Hyun Kim that has since been changed to a no contest. Prior to suffering a second-round knockout to Thiago Alves last April, “The Heat” had won three-straight and eight of his last nine, with his only career losses coming to notables Sean Sherk (twice), Georges St-Pierre, Diego Sanchez, and Alves.

Hazelett (12-4) is coming off back-to-back submission victories over Josh Burkman and Tamdan McCrory, which improved his UFC record to 5-2, but hasn’t fought in over a year after an injury sidelined him from a scheduled March return.

Due to Parisyan’s last-minute withdrawal, Hazelett will not be in action at Saturday’s event and will instead be scheduled to fight on another upcoming card, though the UFC will still pay him his full salary and win bonus.

“Dustin will be paid his full purse to show and win. It’s not his fault,” wrote White.

Machida retained the 205-pound title with a controversial unanimous decision win over Rua in their first meeting at UFC 104 in October.

Machida (16-0) has remained undefeated with eight-straight UFC victories, including wins over Tito Ortiz, Thiago Silva, and then title-holder Rashad Evans.

A PRIDE veteran, Rua (18-4) was upset by Forrest Griffin in his UFC debut in 2007 but rebounded with back-to-back wins over Mark Coleman and Chuck Liddell before falling to Machida in a bout most observers scored in Shogun’s favor.

The rematch was expected to take place in January at UFC 108, but was postponed after Machida underwent surgery to repair a hand injury suffered in his October win.

“Leaving Bismarck, ND right now,” wrote UFC President Dana White on Twitter. “Brock had minor surgery and is feeling better. Not 100% sure he is out of the woods, but feeling better.”

In his latest video blog, White says Lesnar has been released from the hospital and has returned home to recover for several days before undergoing a complete medical checkup in the coming days.

Lesnar, who was also suffering from mono, was scheduled to defend his title against Shane Carwin this Saturday at UFC 106, but the matchup was pushed back to January only to again be postponed as Lesnar remained sidelined.

With Lesnar out indefinitely, White told the LA Times on Tuesday that the UFC will schedule an interim heavyweight title fight, with Carwin and fellow contender Cain Velasquez expected to square off early next year.

Couture (17-10), a five-time champion in the light heavyweight and heavyweight divisions, returned to the 205-pound class on Saturday at UFC 105, scoring a unanimous decision win over Brandon Vera to snap a two-fight losing streak.

Coleman (16-9) is 1-1 since returning to the UFC in January, suffering a third-round TKO to Mauricio “Shogun” Rua before bouncing back with a unanimous decision over Stephan Bonnar in July. He had been slated to take on Tito Ortiz this Saturday at UFC 106, but was forced to withdraw from the bout with an undisclosed injury.

UFC 109, which takes place at the Mandalay Bay Events Center and airs live on pay-per-view, is expected to be headlined by middleweight champ Anderson Silva vs. Vitor Belfort.
