The free-agent offensive lineman has agreed to terms with the Arizona Cardinals on a one-year deal, per the team.
NFL Network's Tom Pelissero reported that the deal is worth $1.4 million. The max is $2 million with playtime incentives. He still gets his $3.4 million from the Vikings too, Pelissero added.
The 30-year-old guard spent last season with Minnesota after six years as a leader along the line for San Francisco. The Vikings parted ways with Boone while trimming their roster down to the 53-man limit on Saturday.
Boone joins a Cardinals team already laced with Mike Iupati and Evan Boehm at the guard position along with Will Holden. At a massive 6-foot-8 and 310 pounds, Boone has a chance to make an impact right away if the coaching staff chooses to shake up the pecking order.
