Just shy of his six-year anniversary with the Houston Texans, the NFL team fired Bill O'Brien on Oct. 5, from his position as head coach and general manager.
Team owner Cal McNair thanked O'Brien for his work with the team.
"Bill's leadership moved our organization forward as he guided us to four AFC South division championships, 52 wins and multiple playoff appearances during his tenure," McNair said in a statement. "Bill proved himself as a coach and leader in this league."
The Texans let O'Brien go a day after the team dropped its fourth straight game to start the 2020 season. Assistant head coach, Romeo Crennel, will serve as interim head coach for the rest of the season.
