Jamison left early in the game with an injury to his right Achilles. Though the severity of the injury is unknown, Achilles' injuries are typically serious. Jamison hasn't been a key cog in Houston's defense, recording just three tackles and one sack through Houston's first six games, but his presence will be missed if the injury is severe.
Caldwell was forced from Sunday's loss with a concussion. Caldwell, who sprained his ankle during Houston's Week 4 win over the Tennessee Titans, will likely be considered week-to-week with the head injury. Houston will host the Baltimore Ravens in Week 7, in a game that could potentially determine homefield advantage in the AFC.
With a bye week in Week 8, it won't be surprising to see the Texans err on the side of caution with Caldwell.
