According to Howard Balzer, the Houston Texans brought in free agent TEs Brandon Barnes and Gabe Holmes for workouts on Tuesday.
Holmes, 26, wound up signing on with the Raiders as an undrafted free agent out of Purdue back in May of 2015. He managed to make the 53-man roster coming out of preseason, but was cut loose just a few weeks later.
The Raiders later signed him to their practice squad after he cleared waivers and elected to bring Holmes back on a one-year, exclusive rights contract this past April.
