Michael Keith Chiesa (//; born December 7, 1987) is an American mixed martial artist, currently competes in the welterweight division in the Ultimate Fighting Championship. A professional MMA competitor since 2008, Chiesa was the winner of FX's inaugural The Ultimate Fighter: Live. As of December 12, 2018, he is #9 in the official UFC lightweight rankings.
Early life and background
Mixed martial arts career
Chiesa began his professional mixed martial arts career in 2008. He fought for several regional promotions in the Pacific Northwest, going undefeated in his first seven fights, before gaining an opportunity to appear on The Ultimate Fighter: Live reality show.
The Ultimate Fighter
Chiesa earned his way into The Ultimate Fighter house, and a $5,000 bonus, with a submission victory over Johnavan Vistante in the elimination rounds. He was chosen as the fifth pick for Team Faber. Chiesa's terminally ill father died shortly after his victory.
After teammate Al Iaquinta picked up the first win for Team Faber, his coach decided that Chiesa would fight Jeremy Larsen next. Chiesa would go on to defeat Larsen by unanimous decision after two rounds.
For his quarter-final fight, Chiesa was matched up with the highly favored prospect, Justin Lawrence. After a hard-fought two rounds, the judges declared a draw and the fight went to a third, "sudden-victory" round. Early in the third round, Chiesa was able to reverse Lawrence on the ground, gain a mount position and win the fight by TKO, earning a $5,000 knock-out bonus and a place in the semi-finals.
Chiesa was selected to fight Team Cruz fighter, James Vick, in the semi-final round. Chiesa won the fight via KO in the second round. He moved on to the finals against Team Faber teammate Al Iaquinta.
Ultimate Fighting Championship
Chiesa officially made his UFC debut at The Ultimate Fighter 15 Finale on June 1, 2012, against fellow Team Faber teammate Al Iaquinta. Chiesa defeated Iaquinta by technical submission due to a rear naked choke 2:47 into the opening round thus becoming The Ultimate Fighter: Live's inaugural winner and received Submission of the Night honors for his efforts.
Chiesa was expected to face Rafaello Oliveira on December 8, 2012, at UFC on Fox 5. However, Oliveira was forced out of the bout with a broken hand and replaced by Marcus LeVesseur. Then, the week of the event, Chiesa was forced out of the bout with LeVesseur with the shingles and the bout was scrapped altogether.
Chiesa was expected to face Reza Madadi on July 27, 2013, at UFC on Fox 8. However, on May 14, 2013, it was announced Madadi was pulled from the bout due to visa issues. Chiesa instead faced Jorge Masvidal. Chiesa was stopped by Masvidal in the second round due to a submission, resulting in the first defeat in his professional career.
Chiesa next faced Ultimate Fighter winner Colton Smith on November 6, 2013, at UFC Fight Night 31. He won the fight via submission in the second round. The win also earned Chiesa his second Submission of the Night bonus award.
Chiesa faced Joe Lauzon on September 5, 2014, at UFC Fight Night 50. After a back and forth fight, Lauzon defeated Chiesa via TKO in the second round after opening a significant cut above Chiesa's right eye, forcing a doctor's stoppage. The performance earned both participants Fight of the Night honors.
Chiesa faced Jim Miller on December 10, 2015, at UFC Fight Night 80. He won the fight via submission in the second round. The bout also earned Chiesa his second Fight of the Night bonus award.
Chiesa was expected to face Tony Ferguson on July 13, 2016, at UFC Fight Night 91. However, Chiesa pulled out of the fight on June 27 citing a back injury and was replaced by promotional newcomer Lando Vannata.
Chiesa faced Kevin Lee on June 25, 2017, at UFC Fight Night 112. At a UFC summer kick off press conference in association with UFC 211, trash talking from Lee about Chiesa's mother ultimately led to punches being thrown, and both were escorted from the stage. Chiesa lost the fight via technical submission at the end of the first round. He appealed to the Oklahoma State Athletic Commission to overturn the defeat, claiming referee Mario Yamasaki erred both in stopping the fight despite no tapout nor loss of consciousness and in allowing Lee to use illegal downward elbows, which cut his head.
Albeit having one fight left on his contract, Chiesa signed a new four-fight deal with UFC on the end of August 2017.
Chiesa was expected to face Anthony Pettis on April 7, 2018, at UFC 223; however, the bout was cancelled after a backstage incident with Conor McGregor on April 5, 2018. McGregor threw a dolly at a UFC bus that Chiesa was travelling on and broke a window. Chiesa was hit by shards of glass and needed hospitalization subsequently resulting in the fight's cancellation.
On September 10, 2018, Chiesa told the media he has sued McGregor for assault, battery and intentional infliction of emotional distress. He also sued Barclay's Center for negligence, although he didn't disclose the amounts or further details of either of the cases. 
The bout with Pettis was rescheduled to UFC 226. At weight-ins, Chiesa weighed in at 157.5 pounds, 1.5 pounds over the lightweight limit of 156 pounds. As a result, the fight proceeded at a catchweight bout and Chiesa forfeited 30% of his purse to Pettis. Chiesa lost the fight via submission in round two. Shortly after the loss, Chiesa announced going up to welterweight division.
