Going for their fourth-straight win, the Dolphins traveled to Ford Field for a Thanksgiving fight with the Detroit Lions.  This game would be marked as Dolphins QB Joey Harrington's return to Detroit, as he was constantly booed throughout the contest.  In the first quarter, Miami trailed as Lions QB Jon Kitna got Detroit off to a fast start.  Kitna would complete a 2-yard TD pass to TE Dan Campbell, while kicker Jason Hanson nailed a 52-yard field goal.  Afterwards, Harrington started to get the Dolphins back into business as he completed his first-ever Thanksgiving touchdown pass on an 8-yard strike to WR Marty Booker.  In the second quarter, Harrington acquired the only score of the period on a 5-yard TD pass to TE Randy McMichael.  In the third quarter, kicker Olindo Mare nailed a 42-yard field goal, while Harrington and Booker connected with each other again on a 19-yard TD pass.  In the fourth quarter, Mare managed to put the game away with a 28-yard field goal. RB Ronnie Brown only had 68 yards rushing (with 5 yards receiving), as he left the game early with a broken left hand. He is currently week-to-week and will likely miss the team's next game against Jacksonville. With the Dolphins victory, not only did the Dolphins improve to 5-6, but Harrington also got his second-ever Thanksgiving Day victory and 1st, 2nd, and 3rd touchdown pass ever on Thanksgiving Day.
