Former UFC title contender Donald “Cowboy” Cerrone returned to the cage tonight for the first time since dropping two fights in a row. Cerrone faced rising up and comer Yancy Medeiros in a wild fight in the main event of UFC on FS1.
Donald Anthony Cerrone (/sɪˈroʊni/; born March 29, 1983) is an American professional mixed martial artist and former professional kickboxer currently competing in the UFC’s Lightweight and Welterweight divisions. He is ranked #13 in the official UFC Welterweight rankings.  A professional competitor since 2006, Cerrone has also formerly competed for the WEC. He is known as the “busiest” fighter in the UFC. Cerrone was born in Columbus, Ohio, of Italian heritage, but he grew up in Denver, Colorado. He was born with Hare-lip which later got fixed. Energetic and troubled in his youth, Cerrone was diagnosed with Attention Deficit Disorder at a young age and would often get into fights as he was growing up. Cerrone attended Air Academy High School which is when he began professional bull riding and it is during this time that his parents divorced, causing Cerrone to live with his grandparents. At the age of 20, Cerrone was introduced to kickboxing and taekwondo by a friend, and compiled an undefeated amateur record of 13-0. Cerrone, who later also began training in Muay Thai, later turned professional, compiling an undefeated record of 28-0 with 18 first-round knockout wins, before transitioning into mixed martial arts.
Cerrone was signed to fight in the WEC. His first fight in the promotion was against Kenneth Alexander. Originally a win via submission in 0:56 seconds of the first round, the decision was changed to a no contest when Cerrone tested positive hydrochlorothiazide, a banned diuretic. Cerrone was scheduled to face Rich Crunkilton at WEC 34, but Crunkilton was forced off the card with an injury and replaced by Danny Castillo. Cerrone won the bout via armbar in the first round. On January 25, 2009, at WEC 38 he fought WEC Lightweight Champion, Jamie Varner, losing via technical split decision. The fight was highly competitive and won the Fight of the Night award. However, the fight was stopped prematurely in the fifth round when Cerrone hit Varner’s temple with an illegal knee while Varner was still on the ground. Varner was given time to recover, but he was unable to continue, noting that he had double vision and had sustained a broken hand.
Cerrone was again scheduled to face Rich Crunkilton on June 7, 2009, at WEC 41, but Crunkilton was forced off the card with an injury and replaced by James Krause. Cerrone defeated Krause via first round submission. Cerrone and Varner had agreed to a rematch, tentatively at WEC 43, but Varner was unable to receive medical clearance as a result from his hand injury. Cerrone fought Benson Henderson for the WEC Interim Lightweight Championship on October 10, 2009, at WEC 43 in San Antonio, Texas, losing by unanimous decision. The fight was awarded Fight of the Year honors by Sherdog for 2009. Cerrone credited Henderson for being “a hell of a fighter” and conceded that he was slow to start the action, which may have cost him the match.
