Transactions roundup: Vikings to add guard Alex Boone

The Minnesota Vikings added some help in front of Teddy Bridgewater.

Former San Francisco 49ers guard Alex Boone has agreed to terms to join Minnesota, NFL Media Insider Ian Rapoport reported, per a source informed of the deal.

ESPN first reported the news.

Boone was Around The NFL's No. 2 guard on the market after Kelechi Osemele, who will sign a massive deal with the Oakland Raiders.

The Vikings sorely needed to upgrade their interior blocking. A plus pass blocker, Boone should help keep Bridgewater upright in 2016 after the quarterback was sacked 44 times and pressured on 46.9 percent of drop backs in 2015. Boone allowed five quarterback hits on 463 pass blocking snaps last season, per Pro Football Focus.
