Miami LB Porter questionable with knee injury

DAVIE, Fla. -- Linebacker Joey Porter has been added to the Miami Dolphins' injury report with a sore knee and is listed as questionable for Sunday's game against New England.

Porter has been bothered much of the season by an injury to his right knee and hamstring. He sat out Friday's drills after practicing earlier this week.

Porter has 4½ sacks in the past two games and leads the Dolphins with seven.

Center Jake Grove sat out practice for the third straight day with an ankle injury and is listed as doubtful. He missed last week's game at Buffalo.

Ricky Williams, who has topped 100 yards rushing in each of the past three games, is listed as probable with a chest injury. He missed no practice time this week.
