The New England Patriots re-signed inside linebacker Bobby Carpenter and released defensive lineman Terrell McClain. Carpenter, a six-year veteran drafted in the first round by the Cowboys in 2006, has played with the Dolphins and Lions since being dealt out of Dallas. He signed with the Patriots in April but was released on Sept. 1 in final roster cuts. McClain was signed last week. The former third-round pick started 12 games with the Panthers in 2011. The Patriots also made two practice squad transactions, signing tight end Alex Silvestro and releasing offensive lineman Thomas Austin.
