Re-examining Miami's offensive line depth

The Miami Dolphins took another tough blow on their offensive line this week. ESPN.com first reported that backup offensive lineman Will Yeatman suffered a significant knee injury in Wednesday’s practice.

So where do the Dolphins go from here?

Yeatman was just beginning to earn playing time as an extra offensive lineman on running plays following the departures of starting right tackle Jonathan Martin and guard Richie Incognito.

Martin left the team on Oct. 28 following a lunchroom incident and later claimed Incognito bullied and harassed him over the past year and a half. The Dolphins suspended Incognito indefinitely.

With Yeatman also out, here is what is left at the offensive line on Miami’s roster:

The offensive line has been a weak link for Miami all year. Losing Incognito, Martin and now Yeatman only makes it worse for the struggling Dolphins, who have lost five of their past six games.

Miami’s starting five up front will remain intact. But Yeatman’s injury may move rookie third-round pick Dallas Thomas to the forefront if there is an injury at offensive tackle in the final seven games. Thomas is green and has been inactive in every game this season.
