Dolphins signed OG Randy Thomas, formerly of the Redskins.

The Dolphins need healthy bodies at guard with Nate Garner (foot) out two months and John Jerry battling knee soreness. Thomas, an 11-year veteran with the Jets and Redskins, missed most of 2009 with a torn right triceps

Dolphins waived WR/KR Ryan Grice-Mullen.

A recent hamstring injury wasn't helping Davone Bess' former teammate at Hawaii, but he was also outplayed by Marlon Moore and Roberto Wallace. Bess remains the heavy favorite to retain punt return duties.

In 1999, Dolphins boss Bill Parcells, who was then the coach of the Jets, picked Thomas in the second round of the NFL draft.

Thomas has started 143 games in 11 seasons since then, including two games last year with the Redskins. Thomas's 2009 season was cut short when he suffered a torn triceps in September.
