Foster, Reed start camp on PUP
Reed is recovering from surgery to repair a partly torn labrum on April 30. Foster strained his right calf early in organized team activities and didn't practice again, but the team said then that he should be ready for training camp.
Receiver DeVier Posey also was placed on the physically unable to perform list. He's recovering from an Achilles tendon injury suffered in Houston's playoff loss.
Houston moved rookies Sam Montgomery, a linebacker, and tackle Brennan Williams to the active roster after they passed physicals. The Texans signed cornerback Elbert Mack and nose tackle Daniel Muir.
