Bill Brady today stepped down as a commissioner with the Nevada State Athletic Commission after eight years on the job.

“To all the things in life there is a season, and I believe my season on the Nevada Athletic Commission must now come to an end, so that another exciting season may begin,” wrote Brady in a letter announcing his resignation (viewable here), effective immediately.

Brady, who served as the influential commission’s chairman before the appointment of current chair Francisco Aguilar, told the Las Vegas Review Journal he had been thinking about resigning for several months, but may have made up his mind in the wake of controversy stemming from this month’s mega-boxing event between Floyd Mayweather and Manny Pacquiao.

“I just don’t have the time or the heart to do it anymore,” Brady said.

Recently, Pacquiao was named as a defendant in a class-action lawsuit for failing to disclose a shoulder injury he suffered prior to the bout. The NSAC forbid the boxer from using an anti-inflammatory shot prior to his fight, which now stands to shatter records as the most lucrative event in the commission’s history.

“I know this man, he has always been an honorable person,” Brady said of Pacquiao. “I find it offensive that he’s being sued and ridiculed. It truly breaks my heart.”

Aguilar told MMAjunkie the commission will continue with its remaining four members until Nevada Gov. Brian Sandoval appoints a new commissioner.

“I think he felt it was time,” Aguilar said. “We’ll definitely have an empty spot. Whenever you have a team, you don’t want to lose a member of that team, especially when you’re making great progress – and I think we were. I was definitely shocked, and I’ll miss him.”

Brady was appointed by now-former governor Jim Gibbons in 2007 and reappointed in 2010 and 2013.

On the commission, he often expressed warmth toward the fighters during disciplinary hearings and was the voice of restraint when it came to meting out punishment.

“The best part of this job was getting to know these fighters as people,” Brady told the Review-Journal. “I had no idea about all the hard work that goes into preparing for a fight. But this position allowed me to see things much differently and gain a true appreciation for what these fighters go through, both in boxing and in MMA.”

Brady’s resignation comes as the commission works to revamp its policies on drug testing and the highly anticipated disciplinary hearings of Anderson Silva and Nick Diaz, who both failed drug tests in connection with January’s UFC 183.
