Texans defensive end J.J. Watt will miss the rest of the season after having back surgery, head coach Bill O’Brien told reporters Friday.
The Texans placed Watt on the injured reserve list on Wednesday. He had the surgery on Thursday.
Watt, 27, underwent back surgery in July to repair a herniated disk. Earlier in the off-season, he also had five torn or partially torn groin and abdominal muscles repaired. He missed the Texans' entire preseason.
Watt, a three-time NFL Defensive Player of the Year, played in the first three games of the season. Before this year, Watt had never missed an NFL game.
To help absorb the loss of Watt, the Texans signed defensive end Antonio Smith this week.
