Randy Couture forever changed the mixed martial arts landscape during a historic run that spanned nearly 15 years.
The former Ultimate Fighting Championship heavyweight and light heavyweight titleholder retired at the age of 47 following a knockout loss to Lyoto Machida at UFC 129 on April 30, 2011. He closed out his remarkable career with a 19-11 record that included victories over a number of contemporaries, including Pedro Rizzo (twice), Vitor Belfort (twice), Chuck Liddell and Tito Ortiz. Couture was inducted into the pioneer wing of the UFC Hall of Fame on June 24, 2006.
