Quarterback Matt Leinart signed a one-year contract with the Houston Texans, the team announced Tuesday.
"We're getting a very smart player who has been productive, and we'll see if we can kind of get the motor going again and all that back. So it's a nice try for us as a football team and it makes us deeper at the quarterback position."
The Texans were looking for insurance at backup quarterback after Dan Orlovsky threw two interceptions in Houston's last preseason game last week. The Texans cut backup quarterback John David Booty, another former USC quarterback, over the weekend despite his two touchdown passes in the preseason finale.
The Cardinals took Leinart with the No. 10 overall pick in the 2006 draft, after he guided the Trojans to two national championships and a third title-game appearance.
