Chiefs running back Kolby Smith, who missed part of last season because of a knee injury, could be in danger of cutting another season short. Head coach Todd Haley acknowledged Friday that the ankle injury Smith suffered two weeks ago could land him on injured reserve. Were having further evaluation, Haley said. Well see. Smith injured the ankle in the win two weeks ago against Pittsburgh, and it was his third game appearance since being activated in early November after recovering from the knee injury.
