ORCHARD PARK — In a stunning development Tuesday afternoon, Russ Brandon has resigned his position as managing partner and president of Pegula Sports and Entertainment, which included his overseeing the operations of both the Buffalo Bills and Buffalo Sabres.

“I have been contemplating transitioning out of my role for some time,” Brandon wrote in a text which was sent to the Buffalo News, the Associated Press, and the Democrat and Chronicle. “My goal when the Pegula’s purchased the franchise was to reach 20 years with the Bills in which I achieved this past November. Given where we are from a timing standpoint, particularly with the conclusion of the NFL Draft, now seems like the time to make that transition. As grateful as I am for the amazing experience and the incredible people I’ve had the privilege to work with the past two decades, I am just as anxious for the professional opportunities that lie ahead."

Brandon’s duties also extended beyond the Bills and Sabres as he also ran the Buffalo Bandits indoor lacrosse team, and the Rochester Americans, the Sabres’ American Hockey League affiliate.

Terry and Kim Pegula released a statement that read: “We have a tremendous amount of confidence in the strong leadership team we have built within each of those entities over the last several years. We are excited about the direction of our teams, especially after this past weekend’s NFL Draft and NFL lottery results. Our focus remains on building championship teams on and off the field for our fans and community.”

There's no official word from the Pegulas on why Brandon is leaving the company.

Beyond the statement he texted, Brandon could not be reached for additional comment, but the Buffalo News reported that his resignation is tied to an internal investigation into Brandon's workplace behavior and allegations of personal misconduct having to do with allegations of inappropriate relationships with female employees at PSE.
