Miami Dolphins running back Ronnie Brown will miss the rest of the season because of a knee injury, his agent Todd France said Monday. Brown underwent an MRI exam Monday. He twisted his right knee in the third quarter of the Dolphins 49-28 loss to the New England Patriots on Sunday. Brown has been one of the few bright spots in Miami's bleak season. Coming into Sunday's game, he led the NFL in yards from scrimmage and had reached the 100-yard rushing mark for four consecutive games. Brown had 76 yards rushing against the Patriots on 17 carries, and had five receptions for 33 yards. The Dolphins are off to an 0-7 start for the first time in their 42 seasons.
