He went on to say "It also doesn’t hurt that he has the great nation of Ireland behind him, and I know they will support him wherever he goes."^[17]

Quigley vs. Reece

Quigley made his professional debut on 12 July 2014 as a middleweight, against Howard Reece at the MGM Grand Garden Arena in Las Vegas. The fight featured on the undercard of Canelo vs Lara, and Quigley won the bout via TKO, just 82 seconds into the first round. "I’m absolutely buzzing", Quigley said afterwards. "I’m delighted to be on a show like this and to win is unbelievable".^[18]

Quigley vs. Najera

Quigley's second professional win came against Fernando Najera, with Najera's corner ending it in the third round.^[19]

Quigley vs. McCoy

On 30 October 2014, Quigley continued his unbeaten start to professional boxing. Fighting in Plymouth, Massachusetts, an area rich with Irish support, Quigley fought Greg McCoy. The fight did not make it out of the first round, with a Quigley left hook, right straight combination sending McCoy to the canvas just 2 minutes and 39 seconds into the bout.^[20][21]

Quigley vs. Dardar

Quigley's first fight of 2015 came as part of Golden Boy's "LA Fight Club", this time held at the Belasco Theatre in Los Angeles. Quigley's opponent was Lanny Dardar in the final fight of the night, and in yet another completely one sided contest, the American received two standing eight counts before an inevitable stoppage just 93 seconds into the first round.^[23]

Quigley vs. Agunbiade

Just two weeks later, Quigley was back in the ring again, this time facing Tolutomi Agunbiade at the Fantasy Springs Resort Casino in Indio, California. The fight was another dominant performance from Quigley, with the referee stepping in 1 minute and 43 seconds into the second round, when it became obvious that Agunbiade was no longer capable of defending himself.^[24]

Quigley vs. Snyder

n 30 April, Quigley returned to the Fantasy Springs Resort to face Joshua Snyder. 44 seconds into round 2, Quigley caught him with a vicious left hook, and followed it up with another big right to confirm the KO over Snyder who was already spiraling towards the canvas.^[25]

Quigley vs. Howard

His next fight was against Mississippi based, Tom Howard. Quigley fought him on 11 July 2015, at the Los Angeles Memorial Sports Arena. The American had won 8 of his 11 professional fights, and had never been KO'd in his career. Despite this, Quigley picked up where he had left off against Joshua Snyder, outclassing his opponent from the first bell. Howard had to pick himself off the canvas twice during the fight, before the referee eventually stepped in and put an end to it in the second round.^[26]

Quigley vs. Faulk

As he returned to the Fantasy Springs Resort Casino for the third time, Quigley fought Michael Faulk, his first southpaw opponent in pro boxing. In a night where The Ring TV commentators dubbed him "El Animal", Quigley continued his perfect record, scoring another emphatic second-round knockout. After a less eventful opening round in which Quigley used his jab and straight right to good effect, Faulk was sent to the canvas three times in the second. Faulk's threw the towel in.^[27][28]

Quigley vs. Adkins

Quigley was taken the distance for the first time in his pro career, when he faced Marchristopher Adkins at the Hard Rock Hotel and Casino in Las Vegas. The American, unbeaten since his first professional bout, was on a six fight win streak in which he became the first fighter to defeat Shane Mosley Jr. Quigley took the four-rounder via Unanimous Decision.^[30]

Quigley vs. Lopez

In February 2016, Golden Boy V.P. Eric Perez confirmed that Quigley would be returning to the ring in late March on another card at Fantasy Springs. Perez stated "he'll fight there and then after that we'll bring him back, possibly on the Canelo card." Canelo is booked to defend his titles against England's Amir Khan, at the new T-Mobile Arena in Las Vegas.^[29] On 26 March, Quigley took on Freddy Lopez, who stepped in as a late replacement for Dante Moore. The fight was another quick finish for Quigley, with him targeting the body from the bell and scoring a knockdown in the first minute. Lopez stood back to his feet only for Quigley to continue the onslaught to his body. It wasn't long before Lopez was down again, giving Quigley another first-round knockout. The victory brought Quigley's record to 10-0, with 9 knockouts.^[31]

Quigley vs. Rosa

On 7 May, in just his 11th pro fight, Quigley took a major step up in class on the undercard of Saúl Álvarez vs. Amir Khan. Quigley faced the then 23-3 James de la Rosa of Mexico, who came in with two camps worth of preparation, having previously been scheduled to face David Lemieux in March.^[32] With Lemieux missing the contracted weight, their fight was scrapped and de la Rosa was instead booked to face Quigley in the Irishman's first 10-round fight. Despite Quigley previously going no further than 4 rounds, he passed his test with flying colors, using quick footwork, precise power punching, and disciplined boxing to hurt and outbox De la Rosa for a dominant and one-sided unanimous decision victory. All three judges scored the fight 100-90.^[33]

Quigley vs. Melendez

On 17 December 2016, Quigley fought on the undercard of Bernard Hopkins last fight against Joe Smith Jr. Quigley faced hard-punching Puerto Rican Jorge Melendez (30-7, 28 KO's). Melendez came out fast but Quigley was able to counter him and Melendez was dropped 3 times in the first round before his corner threw in the towel.

Quigley vs. Tapia

On 23 March 2017, Golden Boy had its first televised card on ESPN following their multi-year deal with the network. The main event featured Quigley taking on Glen Tapia, in what was Quigley's first time ever headlining a nationally televised boxing card. Quigley rocked Tapia badly with a right hand to the chin in the first round, and again with a right hand to the body in the second, but at some point in the second round, Quigley broke his right hand on a shot to the top of Tapia's head, which resulted in a torn tendon.^[34] From this point forward, Quigley could not be as effective with his right hand punches, and it became a fight of attrition. Quigley went back to boxing on the back foot and his superior technical skills earned him another wide unanimous decision (98-92, 99-91, 100-90).

Quigley vs. Mosley

On 29 May 2021, Quigley beat Shane Mosley Jr by majority decision in a 10 round contest. The scorecards were 95-95, 97-93, 96-94 in favor Quigley.^[35]

Quigley vs. Andrade
