Texans add quarterback Brandon Weeden to roster

HOUSTON -- When Houston Texans coach Bill O'Brien said today that T.J. Yates was the team's starter and Zac Dysert was their backup for Sunday, provided Brian Hoyer couldn't go, he placed an emphasis on the words "as we stand here right now."

Things have changed.

The Texans were awarded quarterback Brandon Weeden off waivers today. Weeden was released by the Dallas Cowboys on Tuesday with Tony Romo's impending return. Weeden started three games in Romo's absence and went 0-3, though he played those games without star receiver Dez Bryant.

Dysert is on the practice squad and would have had to be promoted to the active roster to make him available. He admitted today that he isn't totally comfortable with the Texans' offense yet. Practice squad players have scout team responsibilities during practice, running the opposing offense.

Starting quarterback Brian Hoyer is going through the concussion protocol after suffering a concussion against the Cincinnati Bengals.
