HOUSTON -

Wade Phillips was fired as the Houston Texans' defensive coordinator Saturday, a day after Bill O'Brien was hired as the team's head coach.

"Thanks to McNair family and great Texan fans and most all our players," Phillips tweeted. "It was wonderful being home. I wish the best to all.

He also thanked McNair for the treatment of his father, Bum Phillips, who passed away back in October.

Wade Phillips was the interim head coach for the final three games of the season after Gary Kubiak was fired and also directed the team for a game after Kubiak had a mini-stroke Nov. 3 at halftime against Indianapolis. Houston lost its last 14 games to finish an NFL-worst 2-14.

The 66-year-old Phillips, the son of late NFL coach Bum Phillips, spent three years with the Texans. He was the head coach in Denver, Buffalo and Dallas and served as interim head coach with Atlanta and New Orleans.

The Texans hold the number one overall draft pick in May's NFL Draft.

On Friday, the Texans hired O'Brien, the former Penn State head coach and New England Patriots offensive assistant coach, to lead the team.

Phillips had told Local 2 Sports Director Randy McIlvoy earlier this week that he would like to remain with the Texans, but now he will be looking for a new team.

O'Brien Friday said he would be evaluating the current coaching staff on Saturday, and sources tell Local 2 that offensive coordinator Rick Dennison and at least six other coaches were also let go.
