Long injured his triceps during the first quarter of Miami's Week 13 loss to the New England Patriots. Long exited the game and did not return to the field, but was spotted on the sideline wearing a heavy ice pack wrapped around his arm.
Ticketed for unrestricted free agency this winter, Long may have played his last snap with the Dolphins. Long was drafted by Miami with the No. 1 overall pick of the 2008 NFL Draft, and has been named to the Pro Bowl each of the first four years of his career.
If the Dolphins place the franchise tag on Long, it will cost the team over $15 million in 2013.
Rookie right tackle Jonathan Martin replaced Long at left position for the duration of the game against New England, and will likely stay there for the rest of the 2012 season.
