Houston Texans defensive tackle Cedric Killings was able to stand in the hospital on Monday and doctors are confident he'll soon be walking. Killings' progress came one day after he left the field on a stretcher after a headfirst collision with Indianapolis receiver Roy Hall. Killings fractured his C-4 vertebra and was unable to move any of his limbs for a time on the field on Sunday, Dr. Rob Parrish, a neurosurgeon working with Killings, said. He has since gained movement in his arms and legs, though he's weak in both hands and his left arm. "He stood for me this morning at the bed side," Parrish said. "So I think he'll walk out of the hospital. That's very good. We were all applauding." Parrish said the biggest concern now is the weakness in his left arm, but that it was too soon to tell if would be permanent. "That's his deficit right now," Parrish said. "It might all come back."
