On the first play from scrimmage, quarterback Charlie Frye completed a 74-yard touchdown pass to wide receiver Braylon Edwards. However, because of a holding penalty on tackle Kevin Shaffer, the play was called back. The Browns would only manage 56 yards of total offense during the first half of play. By halftime, New Orleans was leading the game 9-0, because of three field goals (43 yards in the first quarter, 25 and 21 yards in the second) by kicker John Carney. In the second half, Frye completed an 18-yard touchdown pass to tight end Kellen Winslow, marking his first career touchdown reception. However, the Saints burgeoned their lead, with opposing quarterback Drew Brees completing a 12-yard touchdown pass to wide receiver Marques Colston. In the fourth quarter, Frye brought the Browns within two points of the lead when he rushed for a 1-yard touchdown. A 20-yard field goal from Carney put the Saints up for good, 19-14. The Browns were threatening in Saints territory as the clock was winding down, but a Frye pass deflected off Edwards' chest and into the hands of safety Josh Bullocks.  With the loss the Browns began their season 0-1.  0-1 against NFC opponents.
