Watch: Texans FB Troy Hairston scores first NFL TD in preseason game vs. Rams

Three years after signing as an undrafted free agent, Troy Hairston found his way into the end zone for his first career touchdown.

Last week, Houston Texans third-year receiver John Metchie III finally scored his first official touchdown in the NFL.

A week later, it was time for Troy Hairston to punch it in for six.

Hairston caught a swing pass from Tim Boyle on the opening play of the second quarter in Saturday’s preseason contest against the Los Angeles Rams for a 5-yard touchdown to give Houston a 10-7 lead.

Hairston, who missed all of last season after suffering a neck injury in practice, is competing for a spot on the active roster. Fullback Andrew Beck might be a lock to make the roster, but Hariston’s value on special teams could push him ahead of newcomer Nick Bawden.

As a rookie still learning how to play the role, Hairston flashed potential in Pep Hamilton’s zone-based scheme. Mostly used on third-down routes, the former Central Michigan linebacker finished with five catches for 19 yards.

The Texans likely will only carry five running backs — including a fullback— on the active roster. Even if Hariston doesn’t make it on the active roster, he’ll be a top candidate to stick around on the practice squad.
