Coming off their home win over the Packers, the Buccaneers flew to Land Shark Stadium for a Week 10 interconference duel with their in-state rival, the Miami Dolphins.  In the first quarter, Tampa Bay struck first as kicker Connor Barth got a 51-yard field goal.  However, the Dolphins would answer with a 1-yard touchdown run from running back Ronnie Brown (with a blocked PAT).  Miami would add onto their lead in the second quarter with a 49-yard field goal from kicker Dan Carpenter.  The Buccaneers would reply with Barth's 50-yard field goal, but the Dolphins would take a huge lead as quarterback Chad Henne completed a 5-yard touchdown pass to tight end Kory Sperry, followed by Carpenter getting a 30-yard field goal. Tampa Bay would get the only score of the third quarter as Barth nailed a 54-yard field goal.  The Buccaneers would creep closer in the fourth quarter as rookie quarterback Josh Freeman completed a 33-yard touchdown pass to wide receiver Maurice Stovall, yet Miami continued to have their way as Carpenter booted a 45-yard field goal.  Tampa Bay would take the lead as running back Cadillac Williams got a 1-yard touchdown run, but the Dolphins got the last laugh as Carpenter made the game-winning 25-yard field goal.
