Texans quarterback Matt Leinart left Sunday's game at Jacksonville with a left shoulder injury and will not return. Leinart was hit hard by defensive end Jeremy Mincey late in the second quarter. T.J. Yates replaced him. Leinart was making his first start in two years after replacing Matt Schaub, who is out for the season with a foot injury. He completed 10 of 13 passes for 57 yards and a touchdown.
