As Brown sits, Texans add RB Bell

Posted by ESPN.com's Paul Kuharsky

My colleague Bill Williamson is reporting that running back Mike Bell has signed a two-year contract with the Texans.
Bell had some success in Denver, averaging 4.3 yards a carry in 2006 while running for eight touchdowns. The Texans' new run scheme will look a lot like the one used by the Broncos.

With Bell in the fold the Texans now have six backs with a chance to contribute. He joins Ahman Green, Chris Brown, Chris Taylor, Steve Slaton and Darius Walker.

Brown is the one slipping, as he has now been out for three consecutive days with a back issue and coach Gary Kubiak said Thursday that the former Titan is still "a few days away at least."
