The Titans have outgained the Texans 164 yards to 46, but they have only a 7-0 lead.
Tennessee has had terrible field position, starting at its own 17, 8 and 6 on its three drives. The first drive ended with a punt, and the second with a missed 42-yard field goal by Randy Bullock.
It completed an 11-play, 94-yard drive.
The Titans thought they scored three plays earlier on a 1-yard run by D'Onta Foreman, but a late flag negated it. Defensive lineman Jeffery Simmons served as a lead blocker for Foreman but failed to report.
The Titans were penalized 5 yards for an illegal substitution.
Tannehill’s touchdown pass came on third-and-goal from the 5.
Texans defensive end Jonathan Greenard injured his foot and is questionable to return.
