HOUSTON (AP) — The Houston Texans have placed star defensive end J.J. Watt and wide receiver DeAndre Hopkins on the physically unable to perform list.

Also going on the PUP list was wide receiver DeAndre Carter.

Watt, a three-time Defensive Player of the Year, reportedly had knee surgery after last season. He shook off two years of injuries after he'd played just eight games total and earned All-Pro honors when he had 61 tackles, led the AFC with 16 sacks, had 25 quarterback hits, 18 tackles for losses and forced a career-high seven fumbles, which tied for the most in the NFL.

Hopkins hurt his right shoulder in the first half of Houston's loss to Indianapolis in an AFC wild-card game. He was second in the NFL with a career-high 1,572 yards receiving during the regular season

The Texans start training camp on July 25 and will open the regular season on Sept. 9 at New Orleans in the first game of a "Monday Night Football" doubleheader.
