Trying to snap a seven-game slide, the Ravens flew to Dolphin Stadium for a Week 15 intraconference duel with winless Miami Dolphins.  In the first quarter, Baltimore took flight early as kicker Matt Stover managed to get a 27-yard field goal for the only score of the period.  In the second quarter, the Ravens increased their lead as Stover kicked a 39-yard field goal.  The Dolphins would get on the board with kicker Jay Feely getting a 23-yard field goal.  Baltimore would end the half as QB Kyle Boller completed a 17-yard TD pass to WR Derrick Mason. In the third quarter, Miami began to rally as RB Samkon Gado got a 7-yard TD run for the only score of the period.  In the fourth quarter, the Dolphins took the lead as Feely kicked a 22-yard and a 29-yard field goal.  The Ravens would tie the game with Stover nailing an 18-yard field goal.  However, in overtime, the Dolphins would seal their first, and only, win of the year as QB Cleo Lemon completed a 64-yard TD pass to WR Greg Camarillo. With their eighth-straight loss, the Ravens fell to 4-10. The win for the Dolphins turned out to be their only victory of the season as they improved to 1-13.
