On Wed., Jan. 20, the Buffalo Bills were apart of National Football League history, as they hired Kathryn Smith as the NFL’s first full-time female coach. The Bills announced on Wednesday that Smith will be the Bill’s special teams quality control coach.

Smith is no stranger to the NFL, as she has been apart of the New York Jets organization since 2003, when she was hired as a game day/ special events intern. In 2005, she was promoted to college scout intern and in 2007 became a player’s assistant.

Current Buffalo Bills Head Coach, Rex Ryan, has worked closely together with Smith since their days with the Jets organization, when Ryan was hired as head coach in 2009. Then Smith made the transition to an administrative position within the Jets organization when she was hired as the team’s administrative assistant in 2014. She followed Ryan to the Bill’s Organization where she spent 2015 as Ryan’s Assistant.

Ryan released a statement on the hiring of Smith as the new assistant.

Kathryn Smith will be replacing Micheal Hamlin, as the Bills released a statement earlier in the month stating that Hamlin would not be returning with the team for the coming year.

Smith has received an enormous amount of support through social media, including current Bill’s defensive lineman Richie Incognito.

Even Barbie has showed her support for Smith.

The Bills are not the only organization in the NFL to break gender barriers, the Arizona Cardinals hired Jen Welter as their line backers coach during last summer’s training camp.

Smith is only one of two active full-time female assistant coaches across the four major sports in the United States. The only other female assistant coach is Beck Hammon for the NBA Franchise San Antonio Spurs. Hammon was a former WNBA player, who was hired by Spurs Head Coach Greg Popovich in 2014.
