JACKSONVILLE - Texans quarterback Matt Schaub left Houston's Week 13 game against the Jaguars early in the first quarter with a dislocated left shoulder. He returned midway through the second quarter.
The injury occured on the Texans' first play from scrimmage when Schaub was sacked by defensive end Derrick Harvey for a loss of one yard.
"He had a dislocation, and they were able to get it back and in and he wanted to come back out to play," head coach Gary Kubiak said. "So it was a gutsy performance on his behalf, (but) we came up a little bit short."
Rex Grossman, who started 31 games for the Chicago Bears from 2003-08, replaced Schaub for four series. Grossman threw an interception on his second play and finished 3-of-9 for 33 yards. His previous last action came with the Bears on Nov. 16, 2008, at Green Bay.
Schaub had surgery on his left shoulder after the 2007 season. The surgery resulted from a season-ending injury suffered on a sack by Titans defensive end Antwan Odom on Dec. 2. Schaub missed four games in 2008 with a knee injury caused by illegal hits by Vikings defensive end Jared Allen.
This was Schaub's 12th start of the season. He played in 11 games in both 2007 and 2008.
