The Patriots announced Thursday they have re-signed free agent linebacker A.J. Edds. Edds spent part of the 2011 season on the New England 53-man roster and the practice squad. The 6-foot-4, 256-pounder originally entered the NFL as a fourth-round draft pick (199th overall) of the Dolphins out of Iowa in 2010. The 25-year-old spent his rookie season on Injured Reserve with a knee injury.
