The Patriots added another rookie free agent to their roster on Friday, signing Montana offensive lineman Jon Opperud.
The 6-foot-7, 300-pound lineman signed with the Seahawks on Apr. 29 but was released on Tuesday.
Opperud was a three-year starter at Montana, first at left guard (2009) and then left tackle (2010-11).
New England's roster now stands at 89 players.
