The Texans placed quarterback Matt Schaub on injured reserve Wednesday and signed Kellen Clemens to take his roster spot.
Schaub sustained a right foot injury during Houston's 37-9 win over Tampa Bay on Nov. 13.
Matt Leinart will be the team's starting quarterback going forward.
Schaub met with several doctors, who determined he'll need season-ending surgery on the Lisfranc injury.
