The Bills announced the hiring of Kathryn Smith as a special teams quality control coach, making her the first full-time female assistant in NFL history.

Smith worked as the administrative assistant to head coach Rex Ryan last season and in 2014, when both were with the Jets. Smith was a player personnel assistant with the Jets for seven years prior and also worked for the team as an intern.

"Kathryn Smith has done an outstanding job in the seven years that she has worked with our staff," said Ryan 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."

The move comes less than a year after the Cardinals hired Jen Welter as a training camp assistant coach.
