Dolphins make moves, more to come
The Dolphins also put in a waiver claim on Cleveland running back Lee Suggs, but have yet to be awarded the player, according to a club source.
With 51 players now on the roster, the team is setting up room for Suggs and another player to claim off waivers.
The Dolphins reached the 53-man roster limit by adding Jacox to the roster before Sunday's practice. Jacox played the past four years with New Orleans after playing four seasons in San Diego.
The reason Miami added Jacox is that neither Toledo (sprained knee) nor Joe Berger (midfoot sprain) are healthy enough to play against Pittsburgh.
But after the practice, the team cut Rader and put Toledo on IR, leaving Miami with 51 players on the roster. Toledo's season is effectively over.
Claiming Suggs is no sure bet. He was traded to the New York Jets earlier in the preseason and failed their physical. He is due to arrive in South Florida today and take a physical.
The Dolphins also added eight players they had previously cut to their practice squad.
The team added receivers Marcus Vick and Fred Gibson, running back Gerald Riggs Jr. and Kay-Jay Harris, offensive tackle Orrin Thompson, tight end Keith Heinrich, cornerback Shirdonya Mitchell and linebacker Matt Sinclair.
