The Texans signed seven players to their practice squad, including former Houston Cougars quarterback Case Keenum. The seven-player list, as reported by Mark Berman of FOX 26 and the Houston Chronicle's John McClain, goes as follows:
Keenum appeared to have the opportunity to win the No.3 quarterback spot on Houston's 53-man roster, but that job went to the more experienced John Beck. The Battle Red Blog expects the Texans to pursue an offensive tackle, but more of a swing tackle, to backup Derek Newton and Duane Brown.
This, from BRB:
I would guess they will go offensive line shopping, as the Texans usually carry an offensive lineman on the practice squad. I would be mildly surprised if they did not add a young, developmental tackle as the final member of the practice squad.
