According to ESPN NFL Insider Adam Schefter, former San Francisco 49ers guard Alex Boone has signed with the Minnesota Vikings.
(Update: Boone signed a four-year, $26.8 million contract with $10 million guaranteed, per a league source, via the Star Tribune.)
The 6-foot-8, 300-pound Boone, who turns 29 on May 4, held out the past two offseasons but has started all but one game he played for the 49ers in the past four seasons (59 of 60), according to the report. He moved from right guard to left guard last season, despite a seeming desire to move out to right tackle.[ESPN, Star Tribune]
