Matt Leinart became the second Texans starting quarterback to be felled by a significant injury in two games, putting the team in dire straits as it attempts to reach the playoffs for the first time.
Jeff Garcia: The four-time Pro Bowl pick is clinging to his NFL dreams at age 41. Though he hasn't started a game in three seasons, he had two solid seasons as a game manager with the Buccaneers in 2007 and '08. He has thrown 161 career touchdown passes, but he's perhaps best known for his run-ins with ex-49ers teammate Terrell Owens and his marriage to a Playboy Playmate.
Brodie Croyle: If this is The Island Of Misfit Toys, Croyle is the choo-choo train with square wheels. In 10 starts for the Chiefs over five seasons, Croyle went 0-10. In the past month, Croyle, 28, has lost QB competitions to Clemens in Houston and Sage Rosenfels in Miami, which might be God's way of telling him something.
Chase Clement: A local guy who played college ball at Rice, Clement spent some time slinging the rock for the Las Vegas Locomotives of the UFL. Clement, 25, has never been associated with an NFL team. Your classic dark (pitch black and disorienting) horse.
