Browns Chief of Staff Callie Brownson will become the first female positional coach in NFL history in Cleveland's game Sunday against the Jaguars in Jacksonville.
Brownson will fill in for Browns' tight ends coach Drew Petzing, who will not make the trip after his wife, Louisa, gave birth to the couple's first child early Saturday morning.
Per NFL policy this season, clubs are required to announce when a member of the coaching staff misses a game for any reason. The club must also announce the name and new responsibility assumed by any coach who has his or her normal game-day responsibilities adjusted in response to such absences.
