After a heartbreaking loss to the Bengals, the Browns headed to Buffalo, the site of their last win in Week 11 of the 2008 season, and trying to avoid tying a franchise record 11 straight losses. In very windy conditions, the Browns' hero was punter Dave Zastudil who pinned the Bills within their 5-yard line 3 times. After trading field goals in the 2nd and 3rd quarters, the Browns recovered a fumble on a punt return by WR Roscoe Parrish, and kicker Billy Cundiff secured the victory with a short field goal. The Browns won despite QB Derek Anderson completing only 2 of 17 passes (11.8%) for 23 yards, setting a record for lowest completion percentage in a win since the AFL-NFL merger. This also marked Eric Mangini's first win as head coach of the Browns. With the win, the Browns improved to 1-4. Zastudil was named the AFC special teams player of the week.
