The Bills signed assistant general manager Doug Whaley to a contract extension, the team announced Saturday.

"I am happy that we have secured Doug's services into the future and look forward to a smooth transition of the position when the time comes,” said GM Buddy Nix. 

Whaley originally joined the Bills’ organization in 2010 as the assistant GM and director of player personnel. He is expected to be the Bills’ GM when Nix retires.

"We are very pleased with the structure of our football operation and look forward to working with Buddy, Doug and the entire staff for many years to come,” said Bills president and CEO Russ Brandon. “As we have stated previously, there is no timetable for the transition. Our focus continues to be on building the foundation for a winning program."
