Rapid Reaction: Colts 17, Ravens 15

BALTIMORE -- The Baltimore Ravens came extremely close to knocking the Indianapolis Colts from the undefeated ranks. But in the process of coming up short, Baltimore's playoff hopes are now in serious jeopardy.

Ravens quarterback Joe Flacco threw a crucial interception deep in Indianapolis territory with under three minutes to go to help the Colts seal a hard-fought, 17-15, victory at M&T Bank Stadium.

The usually cool Flacco came off the field and screamed in frustration after making arguably his worst decision of the season. Baltimore played a great game defensively against Peyton Manning and the high-powered Colts, as the Ravens were in prime position to take the lead late in the game.

Baltimore struggled mightily in the red zone as new kicker Billy Cundiff converted on five field goals. A touchdown on any of those opportunities could have changed the outcome for the Ravens. Cundiff also missed a sixth attempt.

Instead, Baltimore is 5-5 and likely will need to win five of its final six games to have a legitimate chance at the postseason. The Ravens will play the Pittsburgh Steelers, their biggest rival, next week at home in what is shaping up to be a must-win situation for Baltimore.
