The Texans intend to sign either Jeff Garcia or Jake Delhomme Tuesday, a source tells ESPN.com. The two veteran free agents are working out for the Texans today. Garcia also worked out in Houston last week, but the team chose to sign Kellen Clemens instead. Regardless, rookie T.J. Yates will get the first crack at running with the job when he starts against the Falcons on Sunday. Kellen Clemens will be his backup.
