Wrap-up: Chiefs 27, Steelers 24 (OT)

In just two weeks, the Pittsburgh Steelers went from a serious AFC contender to a team that likely will be fighting week to week to just to get into the postseason.

The Steelers suffered their worst loss of the season Sunday to the lowly Kansas City Chiefs, 27-24, in overtime. Chiefs (3-7) receiver Chris Chambers caught a 61-yard pass in the extra period to set up kicker Ryan Succop's game-winning field goal.

Not only did Pittsburgh (6-4) fail to improve its playoff hopes, but Steelers quarterback Ben Roethlisberger suffered a possible concussion, an injury that will have to be monitored closely throughout the week.

The Steelers have a huge game upcoming against the rival Baltimore Ravens (5-5) next Sunday with a lot of postseason implications on the line for both teams. The Ravens' playoffs hopes are on life support, while the Steelers will need a win to avoid a three-game losing streak at a crucial point in the season.
