The Minnesota Vikings just acquired more offensive line depth in the form of tackle Ryan Van Demark. 

ESPN's Kevin Seifert explains the move further with, 

 "Van Demark was a restricted free agent after spending most of his career with the Buffalo Bills, who had tendered him at the lowest level. That gave the Bills the right of first refusal on the Vikings' one-year, $4.2 million fully-guaranteed offer sheet, but on Friday the Bills sent word that they would decline to match. The Bills will not receive compensation, according to ESPN's Alaina Getzenberg."
