Coming off their bye week, the Buccaneers were still looking for their first win of the season. The Bucs traveled to the Louisiana Superdome for their third divisional match-up in a row&#8212;this time, against the New Orleans Saints. The Bucs scored first as rookie QB Bruce Gradkowski threw an 18-yard TD pass to WR Joey Galloway in the first quarter; the Saints responded with a 21-yard field goal from kicker John Carney. The Saints continued scoring, with a 24-yard TD run from RB Deuce McAllister in the second quarter, and a 9-yard TD pass to TE Ernie Conwell in the third quarter. The Bucs finally responded with a 1-yard TD run from FB Mike Alstott, and took the lead in the fourth quarter with Gradkowski's 3-yard TD pass to TE Alex Smith. Unfortunately for the Bucs, a special teams breakdown led to Saints RB Reggie Bush getting his inaugural NFL touchdown on a 65-yard punt return, which sealed the win for the Saints.
