He holds a record of 29-8 with 23 knockouts and 1 draw 1 no contest. He was featured for the first time on the cover of Ring Magazine on the December 2003 issue, released in October.

Shine Fights stated that Mayorga's contract with DKP was for boxing, and as such did not apply to mixed martial arts. Judge Marc Gold granted the injunction just several hours before the fight. Later on the same day, Shine Fights officials conceded defeat in the matter and Mayorga was pulled off the card. At the press conference, He was seen smoking cigarettes and looked a lot heavier than he usually does. Mayorga got under Thomas' skin with his trash talking and by blowing smoke in Thomas' face. Thomas reacted badly having to be held back by members of his camp, then after it settled Mayorga chopped Thomas in the neck^{[citation needed]}.
