Trouble may be increasing for a former UFC lightweight fighter as his temporary suspension has been extended following a positive drug test.
According to a recent report from MMAFighting.comthe Nevada Athletic Commission revealed that Justin Jaynes tested positive for benzoylecgonine, a metabolite of cocaine, following his unanimous decision victory over Marlon Gonzales at Tuff-N-Uff 149 on October 25.
Consequently, “Guitar Hero” was suspended by the committee on November 26 and will remain sidelined until the NSAC determines further disciplinary action. Jaynes could be subject to additional sanctions, including an extended suspension, financial penalties, or even having his win overturned as a no-contest due to the failed drug test.
The commission is expected to revisit the matter at a future meeting, or once an arbitration agreement is finalized, with a ruling possible as early as January.
What was Justin Jaynes’ UFC record?
Justin Jaynes made his Octagon debuted on short notice against Frank Camacho at UFC Vegas 3 in June 2020, where he impressed with a first-round knockout win that also earned him a Performance of the Night bonus.

However, that proved to be the only highlight of Jaynes’ year-long stint in the UFC, as he suffered four straight losses, including three straight losses to Gavin Tucker, Gabriel Benitez and Devonte Smith.
Jaynes’ last appearance in the UFC ended in a split-decision loss to Charles Rosa at UFC Vegas 30 in June 2021, a fight remembered for his infamous decision to bet his entire fight wallet on himself, a move that was still legal at the time and ultimately backfired in dramatic fashion.
Following his 1-4 run in the UFC, ‘Guitar Hero’ landed two additional bouts outside the promotion before snapping the skid with a first-round victory over Carson Hardman at Fierce FC 30 in 2024. He now has a professional record of 17-11, with 15 of his wins coming by way of finish.
