J.J. Watt's 2016 campaign is over.

The Houston Texans star underwent his second back surgery in three months on Thursday, and coach Bill O'Brien confirmed Friday that the three-time defensive player of the year won't be back this season.

Watt underwent surgery in late July to repair a herniated disk.

Watt was placed on injured reserve on Wednesday.

Watt re-injured his back in a 27-0 loss to the New England Patriots last Thursday. He posted a note to his Twitter account on Wednesday detailing his thought process.

The Texans (2-1) host the Tennessee Titans (1-2) on Sunday.
