Deshaun Watson found Will Fuller for a 9-yard touchdown pass in the third quarter, and it pulled the Texans to within 10 points.
On 4th-and-1 at Kansas City 9-yard line, Watson threw a short pass to the right side for Fuller, who raced into the end zone for the score. The Texans tried going back to Fuller for a two-point conversion, but Watson's pass fell incomplete.
The Texans trailed by a 23-13 margin with 3:28 remaining in the third.
It was the third touchdown of the season for Fuller, who returned in Week 4 with a pair of scores against the Titans.
