Jadeveon Clowney left Saturday's wild-card matchup against the Colts with an apparent head injury in the second quarter.

He immediately went into the medical tent and continued to be evaluated.
The Texans trailed the Colts 14-0 after the first quarter and failed to stop the Colts from picking up a first down on their first five third down opportunities.
Clowney returned for the final possession of the half with Houston down 21-0.
