"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."
