Russ Brandon stepped down Tuesday as president of Pegula Sports and Entertainment, which oversees the operations of both the Buffalo Bills and Buffalo Sabres.

According to the Buffalo News, Brandon’s resignation comes as reports of an internal investigation into Brandon’s workplace behavior and allegations of personal misconduct having to do with inappropriate relationships with female employees have begun to surface.

However, in a statement to the media, he made no mention of the allegations.

“I have been contemplating transitioning out of my role for some time,” Brandon wrote in a text that 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.”

In addition to his duties with the Bills and Sabres, Brandon also ran the Buffalo Bandits indoor lacrosse team, and the Rochester Americans, the Sabres’ American Hockey League affiliate.
