No veteran has more to prove to the Texans than running back Chris Brown. His six-year pro career has been hampered by injuries and after signing with Houston as a free agent in 2008, he suffered a back injury that sidelined him for the season. It was frustrating what happened (last year), Brown said. But I know that I have to go out there now and prove my worth and show them that I am healthy. Brown spent the spring in Chicago strengthening his back and now he is looking to be the guy who backs up Steve Slaton. Hes showed in this league he can have some big games and also he should be a good short-yardage player for us, head coach Gary Kubiak said. I could say, Chris, when he has been healthy and been out on the field in this league, hes been successful. The question is keeping him healthy and if we can work him with Steve, we should be able to do that. Source: houstontexans.com
