The Dolphins signed defensive tackle Isaako Aaitui, running back Cameron Marshall, tight end Kyle Miller, tight end-fullback Emmanuel Ogbuehi, offensive tackle Michael Ola, wide receiver Ryan Spadola and offensive tackle Jason Weaver. Ola played in the CFL the past two seasons, while the rest ended 2013 on Miami's practice squad.
The Bengals made a slew of moves Tuesday as they get closer to finalizing the 53-man roster.
Cincinnati waived offensive guard Otis Hudson and tackle Jason Weaver, put linebackers Brandon Joiner (knee) and Sean Porter (shoulder) on injured reserve, and placed quarterback Zac Robinson (elbow) and fullback Chris Pressley (knee) on the PUP list.
The Buccaneers have signed guards Roger Allen and Howard Barbieri as well as linebacker Dom DeCicco. To make room for them they waived cornerback Mason Robinson and tackles Brice Schwab and Jason Weaver.
Additionally, punter Michael Koenen was removed from the Non-Football Injury list.
