The 6-foot-3, 285-pound Jamison played in each of the Texans' first five games, backing up J.J. Watt. Jamison had nine tackles, including a sack, and a deflected pass this season.
Packers linebacker Nick Perry left in the second quarter with a knee injury and was out for the game. Perry was the Packers' fifth-leading tackler (28) and had two sacks through the first five games. Green Bay middle linebacker D.J. Smith limped off the field later in the second quarter with a right knee injury and also was out for the game.
Texans right guard Antoine Caldwell left before halftime with a concussion.
Packers running back Brandon Saine injured a knee playing special teams.
Earlier, the Jets lost two running backs in four plays.
Joe McKnight was hurt on a 61-yard run, three plays after Bilal Powell was lost with a shoulder injury. Both McKnight and Powell were scheduled to have MRI exams Monday.
San Francisco left tackle Joe Staley left with a concussion in the third quarter of Sunday's game against the 49ers.
In Cleveland, rookie running back Trent Richardson was hurt when he took a helmet to the side early in the game, but the Browns got their first win of the season anyway, 34-24 over the Bengals.
Richardson finished with 37 yards on 14 carries and spent most of the second half on the sideline. But Richardson's backup, Montario Hardesty, picked up the slack and rushed for 56 yards and scored his first touchdown in the NFL as the Browns (1-5) also snapped a 12-game losing streak inside the AFC North.
"I took a shot, but I'll be back," said Richardson. "I'll be ready for next week."
