According to Dan Rafael of espn.com, former world champion Joan Guzman has been suspended by the Nevada commission and released by Golden Boy Promotions for a failed urinalysis after his fight with Jason Davis on December 11.
The bout has been ruled a no-contest.
“As you are aware, before your boxing bout in Nevada on December 11, 2010, you voluntarily submitted to a urinalysis and provided a urine sample to Nevada State Athletic Commission representatives,” Wrote Keith Kizer, head of the Nevada Commission. “The results of the urinalysis reflected the presence of Furosemide, which is not approved by the Commission.
“Consequently, please be advised I am filing a disciplinary complaint against you alleging that you violated section 467.850 of the Commission’s regulations, which prohibit the use of any non-approved drug or stimulant before or during a contest of unarmed combat. It is my recommendation that your license be suspended pending formal disciplinary action.”
Upon the ruling, Guzman was released by his promoter Golden Boy Promotions
