Houston Texans defensive end Jadeveon Clowney will not play Sunday against the Titans because of a back injury, a source has confirmed to ESPN’s Adam Schefter.

The NFL Network was first to report the news on Clowney, who is officially listed as questionable.

In a 27-20 loss at New England last week Clowney had two tackles.

Texans wide receivers DeAndre Hopkins and Will Fuller, who also are listed as questionable, will both play, a source tells ESPN’s Adam Schefter.
