He was injured in the second quarter and remained on the ground for several minutes before being helped to his feet and limping to a cart. Houston offensive linemen Chris Myers and Duane Brown walked over and shook his hand as he was being carted off the field.
Baker started 16 games in 2012, but played in just four games last season because of problems with his left knee. He had surgery on that knee in November.
