With Jake Long hitting IR and missing the rest of the season, the Miami Dolphins will have to shuffle things along their starting offensive line. Rookie Jonathan Martin will slide over from right tackle to take Long's spot at left tackle -- where he played in college -- which leaves an opening on the right side.

Omar Kelly of the Sun-Sentinel takes a look at how the Dolphins could go about filling the vacancy. Nate Garner stepped into the starting five after Long went down against the Patriots last Sunday. Head coach Joe Philbin could also opt to move over starting right guard John Jerry, which would require rookie Johs Samuda to step in at the open RG spot.

Philbin said the team is working on a variety of looks and basically holding auditions in practice this week:

"We're looking at a variety of scenarios when we're on the practice field," Philbin said. "Certainly we're going to continue to evaluate what our best options are heading into this ballgame."

The Dolphins placed Long on IR on Tuesday with a triceps injury. Whoever starts on the line this weekend will have their hands full, as Miami (5-7) is in San Francisco to tangle with the fierce pass rush of the 49ers.
