Russ Brandon was in the war room with the Buffalo Bills over draft weekend, but it looks as though it was his last act with either the Bills or Sabres.

Brandon was serving as managing partner and President for both teams.  As of today, that is not the case.  According to The Buffalo News, Brandon has confirmed his resignation with news of an internal investigation into Brandon's workplace behavior and allegations of personal misconduct.

Over his 20 year tenure with The Bills, he has served multiple offices including General Manager from 2008-2009.  According to AP, he was also the lead in negotiating the Bills most recent lease five years ago, which played a critical role in securing the franchise’s long-term future in Buffalo.
