Tito Ortiz (16-8-1 MMA, 15-8-1 UFC) has found the will to save the day.

Just hours after telling MMAjunkie.com (www.mmajunkie.com) that he wasn't going to fight Rashad Evans (15-1-1 MMA, 10-1-1 UFC) in the interest of making the best career choice, it appears the best career choice is to do it anyway.

UFC president Dana White today confirmed via Twitter that Ortiz and Evans will meet in the headliner of UFC 133, which takes place Aug. 6 at Wells Fargo Center in Philadelphia.

It's been a roller coaster of a day for the promotion, as Phil Davis was forced to withdraw from the late-summer headliner due to a knee injury, and Ortiz, who earlier this month saved his job with a first-round submission of Ryan Bader at UFC 132, reportedly declined the fight. A rumored replacement pitting Lyoto Machida against Evans in a rematch of their UFC 98 bout never came to fruition, and for a while, speculation was rampant on who would step into the spot.

More.

As it turns out, Ortiz will grace the marquee opposite Evans.

It's also a chance for both to settle a score. Ortiz and Evans met four years prior at UFC 73 and fought to a draw, though the decision was a result of a point deduction given to Ortiz when he grabbed the fence in the second round of the fight; the bout otherwise would have been scored in his favor.

Ortiz, of course, comes into the rematch with a triumphant win under his belt and a rapid turnaround time – just 35 days will have elapsed between his fight with Bader and UFC 133.

Prior to his UFC 132 win, Ortiz was on the cusp of being released by the UFC after a loss to Matt Hamill at UFC 121, which left him without a victory in nearly five years. After asking the promotion for another shot, he was slated to fight Antonio Rogerio Nogueira at UFC Fight Night 24. But an injury scratched him from the March event, and he was subsequently booked for one last chance against Bader.

Evans, meanwhile, hasn't fought since May 2010 when he defeated former champ Quinton "Rampage" Jackson at UFC 114 in a highly anticipated grudge match. He had been in line to fight then-champ Mauricio "Shogun" Rua at UFC 128 before a knee injury forced him off the card. As Rua healed from his own knee injury, Evans sat out nearly a year waiting for the title shot rather than taking a non-championship bout and risking his shot at the belt. But when he lost the slot due to injury, UFC officials gave it to Jon Jones following his an early-February victory over Bader at UFC 126.

Jones won the title from Rua in dominant fashion at UFC 128, which set up a meeting with Evans, a former training partner with whom he's now had a very public fallout.

But rather than Jones, a "Bones" injury set up a fight with Davis, a former NCAA Division I national wrestling champion. Then the undefeated prospect fell out.

For now, the Chinese fire drill has stopped.
