About Aaron Riley

Born 1980. Aaron Riley is an American mixed martial arts fighter.

Aaron Riley (born December 9, 1980) is a retired American mixed martial artist who most recently competed in the Lightweight division of the Ultimate Fighting Championship. A professional competitor from 1997 to 2013, he has also formerly competed in PRIDE, the IFL, Shooto, and BodogFIGHT. Aside from mixed martial arts, Riley has also competed in boxing (becoming a Golden Gloves champion) and wrestling.

Background Riley was born and raised in Tell City, Indiana. Growing up, he watched the UFC since its first event in 1993, and fell in love with the sport of mixed martial arts. Riley competed in boxing, winning a Golden Gloves Championship, and also competed in wrestling for three years at Tell City High School.

Riley next faced TUF 8 cast member Shane Nelson at UFC 96, losing via controversial first round TKO.

A rematch with Nelson was scheduled immediately, for UFC 101, which Riley won via unanimous decision (30–27, 30–27, 30–27).

At UFC 105 he was defeated by TUF winner Ross Pearson via TKO in the second round after a flying knee by Pearson opened up several cuts on Riley's face. Doctors viewed the cuts on Riley's face, and came to the conclusion that he was unable to continue.

Riley then rebounded with a unanimous decision win over Joe Brammer on May 29, 2010, at UFC 114.

Riley was expected to face UFC newcomer Pat Audinwood on September 25, 2010, at UFC 119, but Riley was forced from the card with an injury and replaced by Thiago Tavares.

Riley was defeated by Tony Ferguson on September 24, 2011, at UFC 135. While the fight was competitive early, Ferguson landed a strong left uppercut, and Ferguson dominated the remaining two minutes of the round. Immediately after the end of the first round, Riley told his corner that his jaw was broken. The fight was declared a TKO victory for Ferguson, as ringside doctors would not allow Riley to continue. Riley had previously suffered a broken jaw when he fought Spencer Fisher at UFC Fight Night 3.

Riley was expected to face Cody McKenzie on May 15, 2012, at UFC on Fuel TV: Korean Zombie vs. Poirier. However, Riley was pulled from the event and replaced by promotional newcomer Marcus LeVesseur.

After nearly two years away from the sport, Riley returned to face Justin Salas on July 27, 2013, at UFC on Fox 8. He lost the back-and-forth fight by split decision. He retired from MMA following his loss to Salas.
