HOUSTON (AP) — Romeo Crennel announced his retirement Monday, ending a 39-year NFL coaching career that included five Super Bowl titles. Crennel spent the past eight seasons with the Houston Texans. He was the team’s defensive coordinator from 2014-16 and assistant head coach from 2017-19. In 2020 he was the associate head coach before becoming the interim head coach after coach Bill O’Brien was fired after just four games.
