The Miami Dolphins suspect that standout left tackle Jake Long has torn his triceps muscle and will be out for the season,'s Jeff Darlington reported Sunday.

Darlington reported that Long, who left Sunday's 23-16 loss to the New England Patriots with the injury, will have an MRI on Monday to determine the extent of his injury. But the Dolphins appear pessimistic. One source told Darlington that it "doesn't look good."

Despite the loss Sunday, the Dolphins remain in the hunt for a playoff spot. Miami sat 1.5 games behind both the Pittsburgh Steelers and Cincinnati Bengals, who were playing late-afternoon games on Sunday. Without Long, the Dolphins would face even more of an uphill battle to make the playoffs.

If Long is indeed out for the remainder of the season, it could also be the 2008 No. 1 draft pick's final snap with Miami. He is an unrestricted free agent after the season. And though the Dolphins could place their franchise tag on him, it would cost them nearly $16 million to do so. The Dolphins drafted tackle Jonathan Martin in the second round of the 2012 NFL Draft. He has played this season as the team's right tackle, but he was a left tackle at Stanford.
