The Buffalo Bills made history Wednesday by hiring the NFL’s first female full-time coach, naming Kathryn Smith as a special teams quality control coach.

Smith served as the administrative assistant to head coach Rex Ryan this season after working for 12 years for the New York Jets, including the final six with Ryan as Jets head coach.

“Kathryn Smith has done an outstanding job in the seven years that she has worked with our staff,” Ryan said in a statement. “She certainly deserves this promotion based on her knowledge and strong commitment, just to name a couple of her outstanding qualities, and I just know she’s going to do a great job serving in the role of Quality Control-Special Teams.”

Smith served as the administrative assistant to head coach Rex Ryan this season after working for 12 years for the New York Jets, including the final six with Ryan as Jets head coach.

Smith joined the Jets in 2003 as a game-day/special events intern before being named a college scouting intern in 2005 and a player personnel assistant in 2007. She became the assistant to Ryan in 2014.

Smith replaces Michael Hamlin, who the Bills announced earlier this month would not return as special teams quality control coach.
