After trying out fullbacks to replace the injured Boomer Grigsby on Monday, the Texans signed Jonathan Evans, who played at Baylor. Evans was on the practice field Tuesday. Coach Gary Kubiak said even though Evans had been signed, tight end James Casey will still get reps at fullback.

Texans Fullback Boomer Grigsby, who suffered a high-ankle sprain in the second half, will likely miss six weeks

Rex Grossman is expected to miss about a month with a hamstring injury and the Texans are looking to sign another quarterback to fill in until he's healthy.

Grossman, the Texans' third quarterback and the former Bears starter, was injured in Saturday's win over the Chiefs and coach Gary Kubiak says he doesn't feel comfortable finishing the preseason with only Matt Schaub and backup Dan Orlovsky.

Kubiak says the Texans could bring back Alex Brink, who was with the team last season.

Also injured Saturday were safety Troy Nolan, a rookie seventh-round pick, who will have surgery to repair a broken hand on Monday and fullback Boomer Grigsby who is expected to be out six weeks with a high ankle sprain.

The worst of the Texans injuries appeared to be tight end Joel Dreessen (hyperextended knee), safety Troy Nolan (broken hand), fullback Boomer Grigsby (sprained ankle) and quarterback Rex Grossman (pulled hamstring).
