Dolphins signed WR Ryan Spadola, RB Cameron Marshall, TE Kyle Miller, H-Back Emmanuel Ogbuehi, DT Isaako Aaitui, OL Michael Ola, and OT Jason Weaver.

Spadola appeared in three games on special teams with the Jets this year and ended the season on Miami's practice squad. He'll compete for a reserve role in 2014.

Dolphins promoted WR Ryan Spadola from the practice squad.

An undrafted rookie out of small-school Lehigh, Spadola will take Brandon Gibson's roster spot, but not his role. If Spadola is active Thursday evening, his contributions will be limited to special teams.
