Vikings sign DT Green

The Vikings added some depth at defensive tackle with the signing of Howard Green, a veteran of three NFL seasons with Baltimore (2002) and New Orleans (2003-04) who was in camp with Miami last summer.

They also added to their coaching staff, naming Derek Mason assistant defensive backs coach.

Mason, who played defensive back at Northern Arizona when Vikings coach Brad Childress was an assistant there, brings 13 seasons as a college assistant, the last two as wide receivers coach at Ohio University.

Green (6-2, 320) played under Vikings defensive line coach Karl Dunbar at LSU.
