Romeo Crennel is calling it a career after 50 years of coaching football, including 39 years in the NFL.
Crennel, 74, had two stints as an assistant with the New England Patriots. He worked as the defensive line coach from 1993-96 and the defensive coordinator from 2001-04, helping the team to three Super Bowl titles.
He also served as head coach of the Cleveland Browns and Kansas City Chiefs, as well as the Houston Texans' interim head coach in 2020.
"Football has been my entire life and it's been a dream come true to coach for 50 years," Crennel said in a statement.
