with a fourth punch, when referee Herb Dean ended it. Hall of Fame and Hughes vs. Almeida On May 28, 2010, Hughes was inducted into the UFC Hall of Fame. Fighting Renzo Gracie student and 3rd degree Brazilian Jiu-Jitsu black belt Ricardo Almeida, Hughes rendered him unconscious with a Dave Schultz front headlock at 3:15 of round 1, on August 7, 2010, at UFC 117: Silva vs. Sonnen. Hughes landed a huge left hook that knocked Almeida down, sinking in the very deep choke which earned him the Submission of the Night honors. Almeida requested the fight after watching his mentor lose to Hughes at UFC 112 back in April. Hughes now had four wins over mixed martial artists with ties to the Gracies, including UFC pioneer Royce Gracie, the prior mentioned Renzo Gracie and former champ Serra. Hughes vs. Penn III Hughes faced BJ Penn on November 20, 2010, in a rubber match at UFC 123: Rampage vs. Machida, after their previous two fights at UFC 46 and UFC 63. Penn came out strong in the first few seconds of the opening round, catching one of Hughes's kicks and knocking him off balance with a counter hook. Penn then connected with an overhand right that dropped Hughes, following up with three clean shots to the jaw. The bout was ended at 21 seconds into the first round, with Hughes trilogy against Penn ending at 1–2. The fight marked the first time Hughes had been knocked out (he had previously lost via technical knockout). Post-fight Hughes hinted that the loss moved him one step closer to retirement. Hughes vs. Koscheck Hughes was expected to face Diego Sanchez on September 24, 2011, at UFC 135: Jones vs. Rampage. However, Sanchez missed the bout with an injury and was replaced by Josh Koscheck. Hughes suffered a KO loss to Koscheck at 4:59 of the first round. Hughes showed improved striking, but ultimately succumbed to Koscheck's power punches. Retirement The UFC announced on January 24, 2013, that Matt Hughes retired from fighting and was named a Vice President of Athlete Development and Government Relations. Theme music In the UFC, Hughes frequently used the song "A Country Boy Can Survive" by Hank Williams, Jr. as he made his entrance towards the Octagon. At the UFC 56 live broadcast, Joe Rogan said: "My favorite walk-out song in all the UFC, ′A country boy can survive.′"
