Bush hasn't played since he broke his right leg during a Week 2 victory over the San Francisco 49ers. If Bush looks good in pre-game workouts and can play, Payton said the running back will be "all in," also returning punt returns in a rotation with Lance Moore.
Payton sounded less optimistic about rookie cornerback Patrick Robinson's chances of playing, The Times-Picayune reported. Robinson, the Saints' first-round draft pick out of Florida State, suffered a right ankle injury during a Week 8 victory over the Pittsburgh Steelers, and his status for Sunday also will be a game-time decision.
Bush and Robinson both were listed as questionable on the injury report released Friday.
The Saints won't have long snapper Jason Kyle for Sunday's game -- or the remainder of the season -- after placing the 16-year NFL veteran on injured reserve Saturday with a shoulder problem. The team signed former New England Patriots long snapper Jake Ingram as Kyle's replacement.
