Former Ultimate Fighting Championship (UFC) Light Heavyweight Champion Forrest Griffin rose to power in the 205-pound division after winning the infamous "six-figure" contract on the inaugural season of The Ultimate Fighter (TUF).

This is his story.

FUEL TV is bringing mixed martial arts (MMA) fans a closer look at the former Georgia police officer with "Forrest Griffin: The Ultimate Fighter" documentary, which airs TONIGHT (Sept. 5, 2012) at 11:00 p.m. ET on the cable television network.

Griffin (19-7) is 10-5 under the UFC banner, and broke the hearts of PRIDE fans everywhere with back-to-back wins over Mauricio Rua (UFC 76) and Quinton Jackson (UFC 86). His fight against "Rampage" is the one that netted him gold, which he promptly coughed up to Rashad Evans at UFC 92 just a few months later.

Griffin's status as a fan favorite; however, took a hit last July at the UFC 148 pay-per-view in Las Vegas, Nevada.

After a close, back-and-forth fight against Tito Ortiz in their rubber match, Griffin stormed out of the cage in disgust, before ZUFFA brass ordered him back into the Octagon for the official decision. Once he was announced as the winner, he ripped the microphone from the hands of UFC color commentator Joe Rogan and conducted his own post-fight interview.

Then it was disclosed he was the latest member of the TRT club.

UFC President Dana White, who insists the best-selling author "has nothing left to prove," called for his retirement from active competition. Instead, Griffin went ahead with a rematch opposite Chael Sonnen booked for UFC 155 on Dec. 29, 2012, in "Sin City."

The last chapter has yet to be written in Griffin's career, but you can find out how the story has unfolded thus far by heading over to FUEL TV later this evening.
