The Vikings made a tender offer to restricted free agent offensive tackle Mike Harris earlier today, according to an NFL source. As the lowest tender possible, the $1.542 million offer for this season gives the Vikings the right of first refusal only should Harris receive an offer from another team when free agency opens at 3 p.m.

Under the deal, the Vikings would receive no compensation if another team were to sign him. Since Harris entered the NFL as an undrafted player, it would have taken at least a mid-tier offer of $2.356 million to receive a second-round pick as compensation.

Meanwhile, as expected, the team did not make a tender offer to linebacker Dom DeCicco, who arrived last May and was placed on injured reserve last August.

Harris, 26, is a 6-5, 318-pounder who has played in 28 regular season games. He started five games last year at right tackle when Phil Loadholt was injured. He also played more than three quarters at right guard when Vladimir Ducasse and center John Sullivan were injured on the same play. Joe Berger, the only backup interior lineman active that day, came in to replace Sullivan, while Harris stepped in at guard for the first time since his youth football days.

DeCicco and Harris were the only RFAs left to address after the Vikings agreed to terms on a one-year deal with running back Matt Asiata on Monday night.
