The Cleveland Browns headed south to the Louisiana Superdome for their Week 7 battle against the defending Super Bowl champion New Orleans Saints. Cleveland struck first, on a 23-yard field goal by kicker Phil Dawson and a 4-yard run by running back Peyton Hillis to take a 10-0 lead after one quarter. In the second quarter, New Orleans closed the gap on a Garrett Hartley-yard field goal, but the Browns answered with another Dawson field goal and a 30-yard interception return by linebacker David Bowens to push the lead to 20-3 at the half. Special teams played a large role for the Browns in the half, with a 62-yard punt return by Eric Wright thanks to a Josh Cribbs lateral, and a 68-yard rush on a fake punt by punter Reggie Hodges both leading to field goals. In the fourth quarter, quarterback Drew Brees connected with tight end David Thomas to pull within 10, but another Dawson field goal and a second Bowens interception return sealed the win for the Browns. With the win, the Browns entered their bye week at 2-5.  This win also marked the third consecutive season in which the Browns defeated the defending Super Bowl champion.
