CLEVELAND - There's nothing Super about the Pittsburgh Steelers anymore.

The defending NFL champions lost their fifth straight and had their playoff hopes sacked by the lowly Cleveland Browns, who ended a 12-game losing streak against their bitter rival by beating the Steelers, 13-6, last night in subzero wind chills.

Ben Roethlisberger was sacked eight times and lost for the first time in 11 career games against the Browns (2-11), who extended Pittsburgh's longest losing streak in 6 years and defeated the Steelers (6-7) at home for the first time since 2000.

Pittsburgh's postseason chances are in peril - if not over completely. The Steelers are going to need help to make the postseason, a stunning collapse for a team that hit the season's halfway point at 6-2.

Losses to Kansas City, Oakland and Cleveland - three of the NFL's worst teams with a combined record of 9-28 - have pushed Pittsburgh to the brink playoff elimination.

Chris Jennings, who began the season on Cleveland's practice squad, scored on a 10-yard run and Phil Dawson kicked a pair of 29-yard field goals for the Browns, who snapped a seven-game losing streak.

Roethlisberger tried to rally the Steelers, but his fourth-down pass to Santonio Holmes with less than 2 minutes left was knocked down by linebacker David Bowens.
