Fullback Naufahu Tahi has signed his restricted free agent tender, according to this Vikings.com blog.

Safety Eric Frampton, defensive tackle Fred Evans and offensive lineman Ryan Cook signed their RFA tenders on Monday as veterans reported to Winter Park for voluntary offseason workouts.

That leaves defensive end Ray Edwards and quarterback Tarvaris Jackson as the Vikings only restricted free agents who have yet to sign their tenders. Thursday is the deadline for RFAs to sign offer sheets with other teams.
