The Texans are set to waive Vaughn, Aaron Wilson of KPRC 2 Houston reports.
Vaughn's time with the Texans was brief, as he signed a contract with the team less than a week ago. In his only preseason appearance, he rushed 12 times for 36 yards and caught both of his targets for six yards. Vaughn is a candidate to catch on with Houston's practice squad if he goes through waivers unclaimed.
