"Jake Long's week began on a stationary bike. It will end with a significantly more taxing physical assignment.

On tap for the Dolphins' standout left tackle Sunday at Lambeau Field is a Packers' defense that has excelled at getting to the quarterback. Only the Titans (22) have totaled more sacks than the Packers (21), who are pacing the NFL with 148 sack yards.

Eight different Packers have a recorded at least one sack, but one in particular has caught Long's eye. Clay Matthews (hamstring) is listed as doubtful for Sunday's game, but Long is counting on having to contend with the second-year linebacker.

Matthews leads the NFL with 8.5 sacks. In week two against the Bills he became the first Packer to record consecutive three-sack games since it became an official stat in 1982.

"I'm going in with the mindset he's going to play, so I've been watching a lot of film on him and excited for that challenge," Long said. "One of those guys that plays to the whistle or through the whistle. He seems like he never gets blocked. If he's into a block he's always trying to rip off or spin off. A big, strong, very relentless player.""
