The Texans placed running back Domanick Davis on injured reserve Saturday, ending his 2006 season. Davis, Houston's top rusher for the last three seasons, has been out for a month with a bone bruise that is causing soreness in his knee. Texans coach Gary Kubiak decided that putting him on injured reserve would be the right thing for the team, but isn't happy about the decision. "He's done everything he can do," Kubiak said. "It's been disappointing for him and disappointing for everybody."
