Tye Fields grew up in Beaverton, Oregon. Fields played college basketball and was a starter at forward for San Diego State University. Fields never was an amateur. Standing at 6 feet and 8 inches and weighing around 275 lbs (125 kg), the southpaw Fields was considered large even for the heavyweight division.
In his professional career he has beaten some notable opponents such as Andy Sample, Saul Montana, Bruce Seldon, Sedreck Fields, Sherman Williams, Maurice Harris, Konstantin Airich, Raphael Butler and Michael Sprott. He started his career with a streak of 17 consecutive KO victories (16 of them coming in the first round) before he suffered his first loss to Jeff Ford via a 1st-round KO. He would later avenge this defeat by knocking out Ford in a rematch, also in the 1st round. In total Fields has 26 first-round knockouts among his 49 professional victories. He has won 4 regional titles.
On June 28, 2008, Fields faced off against Monte Barrett on the Manny Pacquiao – David Díaz undercard at the Mandalay Bay in Las Vegas. Fields suffered the second defeat of his career losing via knockout after just 57 seconds of the first round when Barrett (34–6, 20 KOs) delivered a series of accurate right hands, knocking Fields down and leaving him unable to beat the referee's count.[1][2]
Following the defeat to Barrett Fields rebounded with 4 straight KO victories over lowly regarded opposition before taking another step up and challenging former heavyweight title challenger Michael Grant. The fight took place on March 11, 2011 at the Planet Hollywood Resort and Casino in Las Vegas. As with his previous step up in opposition Fields came up short when he was knocked out with a single punch from Grant in the third round.

After winning his opening 2 bouts against Michael Sprott and Konstantin Airich he matched up against the undefeated former Cuban amateur star Mike Pérez. Perez won the tournament and the £32,000 prize money when he knocked Fields out in the first round.
On October 7, 2011, Fields defeated a strong puncher Raphael Butler (35–10, 28 KOs) from Minnesota in the 6th round via technical knockout in 10-round main event on KO Boxing's Show of Force card at the Shaw Conference Centre in Edmonton, Alberta, Canada.
