NEW ORLEANS -- New Orleans Saints running back Reggie Bush has been held out of practice for the third straight day, and is listed as questionable for Sunday's game in Tampa Bay.

Bush came out of the St. Louis game with swelling and soreness in his left knee, which was surgically repaired twice in a three-month span a year ago.

Saints coach Sean Payton says Bush's knee is bruised and swollen. He says that happens with a knee that has had surgery.

Payton said Bush knows the offense well enough that he could step in without the practice reps. But at the same time, he doesn't want to risk a setback with his star running back.
