The Buffalo Bills will not retain assistant coach Kathryn Smith for the upcoming season under new coach Sean McDermott, the team announced Tuesday.
Smith became the first woman in NFL history to serve as a full-time coach when former Bills coach Rex Ryan hired her to a special-teams quality control role in January 2015.
Upon being hired to replace Ryan last month, McDermott announced he would retain special-teams coordinator Danny Crossman from Ryan's coaching staff. It is unclear whether Smith, who helped Crossman coach the Bills' special-teams units last season, was interested in returning to the same role as part of McDermott's staff.
