Trying to snap a six-game losing skid, the Ravens stayed at home for a Week 14 Sunday Night duel with the Indianapolis Colts in the rematch of last year's AFC Divisional game.  In the first quarter, Baltimore trailed early as Colts QB Peyton Manning completed a 34-yard TD pass to WR Reggie Wayne, while RB Joseph Addai got a 1-yard TD run.  Afterwards, Indianapolis' Manning completed a 19-yard TD pass to Addai, while CB Michael Coe blocked a punt, causing it to go out of bounds through the Ravens' endzone for a safety.  In the second quarter, the Colts' Addai ran for an 11-yard TD run.  Baltimore responded with rookie WR Yamon Figurs returning the ensueing kickoff 94 yards for a touchdown.  Afterwards, Indianapolis struck again with Manning completing a 57-yard TD pass to WR Anthony Gonzalez. In the third quarter, the Colts' Manning completed a 40-yard TD pass to Gonzalez for the only score of the period.  In the fourth quarter, the Ravens' QB Kyle Boller completed a 4-yard TD pass to WR Devard Darling, while rookie QB Troy Smith got a 6-yard TD run. With their seventh-straight loss, Baltimore fell to 4-9 and to last place in the AFC North with the Bengals' win over the Rams.
