Houston Texans injury update: Tim Jamison done for year with torn Achilles

Houston Texans defensive end Tim Jamison is done for the season after he suffered an Achilles tendon tear during his team's 42-24 loss to the Green Bay Packers on Sunday, according to the Houston Chronicle's John McClain.

As part of one of the NFL's best defensive fronts, the four-year pro out of Michigan recorded three tackles this year as a backup to J.J. Watt. Rookie end Jared Crick will likely see an increased role for Houston.

Meanwhile, cornerback Johnathan Joseph is listed as day-to-day with a sore groin.

Gary Kubiak said CB Johnathan Joseph has a groin injury and will be day to day. "We'll have to be smart with him to get him to Sunday."

Joseph has 29 tackles and an interception this season.

McClain also reports that right guard Antoine Caldwell is currently undergoing the NFL's concussion protocol after suffering a concussion in the first half the game against Green Bay.
