Texans defensive tackle Cedric Killings was taken off the field on a stretcher Sunday after a headfirst collision with Indianapolis receiver Roy Hall. The 6-foot-3, 310-pound Killings, playing special teams, hit Hall on a block as Jerome Mathis was returning a kickoff in the second quarter. The Texans said Killings suffered a neck injury, but had feeling in his extremities. Killings was taken to a hospital.
