Houston Texans quarterback Matt Schaub has a significant foot injury that will force him to the whole season, according to ESPN.com.

The loss of Schaub, who has started every game since the start of the 2009 season, could affect the team's ability to make a dominating playoff push, despite the Texans playing in an average AFC South this year. The Texans are 7-3, tied with the Pittsburgh Steelers for the AFC's best record after 10 weeks, with Schaub a considerable part of their success. He was a top-ten QB in yards (2,479), touchdowns (15) and rating (96.8) for a Texans team that many believe has the capabilities to finally clinch the franchise's first playoff berth.

According to ESPN.com, Coach Gary Kubiak said earlier Monday that Schaub was out indefinitely after injuring his foot on a quarterback sneak during Houston's 37-9 win over Tampa Bay on Sunday. 

Backup QB Matt Leinart will start against the Jaguars after the bye, Kubiak said. The Texans will have to rely on Leinart, who hasn't seen any playing time this year and has been for the most part obscured ever since his fallout with his former team, the Arizona Cardinals.

However, while the Texans may downgrade with Schaub's injury, Schaub's best target, Andre Johnson, will certainly keep the Texans on track Johnson, who has been out with a hamstring injury for six straight weeks, will be ready to return after Houston's bye this Sunday to face the Jacksonville Jaguars on Nov. 27.
