Moore appeared in all eight games this season as a reserve and saw extensive action Sunday in London against the Rams after Kyle Arrington was knocked from the game early with a head injury. The team was already without starting safeties Patrick Chung and Steve Gregory and was using corner Devin McCourty at safety. Moore's release likely indicates the injured members of the secondary figure to be ready for the second half of the season following the bye.

Both Martin and Rivera spent time with the team previously this season. Rivera made the roster out of camp and appeared in the first two games before being let go Sept. 19, while Martin was released after training camp. Both players project as special teamers and depth players on defense.

The Patriots also announced tight end Alex Silvestro was released from the practice squad.

In addition, ESPNBoston.com reported the team conducted workouts for several players. Among them were kickers Billy Cundiff, Neil Rackers and Graham Gano, punters Chas Henry and Ryan Donahue, guard Ryan Durand, running back Lorenzo Booker, long snapper Bryce Davis and wide receiver Jarred Fayson.
