Jason La Canfora of NFL Network reports the Texans have placed quarterback Matt Schaub on Injured Reserve.
As a result, they have inked quarterback Kellen Clemens to be their third quarterback behind Matt Leinart and rookie fifth-round draft pick T.J Yates, according to John McClain of the Houston Chronicle.
According to McClain, he knows system after being with the Redskins in camp and preseason.
More on Clemens: A 2006 second-round pick (49th overall) out of Oregon by the Jets, Clemens started nine of 25 games, completing 51.8% of 284 pass attempts for 1,686 yards with five touchdowns and 11 interceptions over five seasons with the Jets.
In 2011, Clemens went to training camp with the Redskins, completing 18-of-33 pass attempts for 203 yards with one touchdown and one interception in four preseason games before he was released as part of their final roster cuts.
Since the start of the regular season, Clemens has had workouts with the Dolphins (10/6), Raiders (10/19) and earlier this week was one of five quarterbacks to work out for the Texans.
