Kansas City Chiefs cornerback Dunta Robinson could miss Sunday's game against the Dallas Cowboys as he tends to a personal issue. NFL Media Insider Ian Rapoport reported Saturday that Robinson is with his cousin who was in a car accident and remains hospitalized. A source who has been in contact with Robinson told Rapoport that the cornerback is 50-50 to play against the Cowboys. Robinson's cousin has slipped into a coma and is in intensive care requiring the assistance of a breathing machine according to ESPN which first reported the story. Robinson was absent from practice this week for undisclosed personal reasons and was listed as questionable on the Chiefs' injury report. He has not been officially ruled out.
