"It's been a good eight years, I guess. Biggest thing I've learned ... when [UFC president] Dana White says retire otherwise you will blow your knee out," Griffin said at the press conference.
Griffin's last fight was a win over UFC Hall of Famer Tito Ortiz in July of 2012. Coincidentally, it was Ortiz's last bout before retirement. He won that fight by decision. His career included 19 wins, 7 losses and stint as the UFC light heavyweight champion.
What Griffin will always be remembered for is being one-half of a fight that catapulted the UFC into fame. He and Stephan Bonnar were finalists on the first season of the UFC's reality show, "The Ultimate Fighter." Their fight was a close, thrilling battle that played on Spike TV on April 9, 2005.
It was responsible for earning the UFC many fans, which helped earn bigger sponsors and television deals. Griffin won the decision, taking the title of the first "Ultimate Fighter," but both fighters were given contracts.
During the media scrum following the press conference, White said that Griffin and Bonnar will be inducted into the UFC Hall of Fame together.
Griffin went on to be a force in the 205-lb. division, upsetting Pride star Mauricio "Shogun" Rua in 2007, then taking the belt from Quinton "Rampage" Jackson in July of 2008. He lost the belt to Rashad Evans that December.
White said Griffin will continue to have a role with the UFC.Read More »from Original ‘Ultimate Fighter’ Forrest Griffin retires
