Lamar cornerback Brendan Langley worked out privately for the Texans, according to a source not authorized to speak publicly.
Langley is an intriguing size-speed draft prospect who played in the Senior Bowl all-star game.
A transfer from Georgia, Langley is a converted wide receiver and a Football Championship Subdivision All-American selection.
At the NFL scouting combine, Langley ran the 40-yard dash in 4.43 seconds. The 6-foot, 201-pounder bench pressed 225 pounds 22 times and had a 35 1/2 inch vertical leap. He also registered a 10-2 broad jump.
A former Georgia starter, Langley intercepted six passes last season at Lamar and broke up seven passes.
