The Vikings have signed offensive lineman Pat Brown to a one-year contract extension. Brown was set to become an exclusive rights free agent next month. But that designation basically means that, due to Brown's two-year tenure in the NFL, the Vikings would have been the only team in the league able to sign him for 2012. Which they have now done.
Brown saw limited action last season, playing mostly on special teams. He was originally undrafted out of Central Florida in 2009.
The Vikings now have 17 players due to become free agents when the market opens on the afternoon of March 13. The most notable players on that list are linebackers E.J. Henderson and Erin Henderson, tight end Visanthe Shiancoe, safeties Husain Abdullah and Tyrell Johnson and receiver Devin Aromashodu.
Running back Lorenzo Booker and linebacker Kenny Onatulu are both set to become restricted free agents, which will give the Vikings an opportunity to match offers that come from other teams.
