AP source: Vikings get deal with ex-49ers guard Alex Boone (Yahoo Sports)

The Minnesota Vikings have found some feistiness and experience for their unsettled offensive line, a step toward galvanizing a position group that has been lagging the last three years. Former San Francisco 49ers left guard Alex Boone agreed Wednesday to a four-year contract, according to a person with direct knowledge of the deal. The person spoke to The Associated Press on condition of anonymity because the Vikings had not yet announced the signing.
