Fooch's Note: MM is reporting the deal is actually four new years, so through 2015.
Jason LaCanfora is reporting that the San Francisco 49ers worked out a four year contract extension for backup offensive tackle Alex Boone. The 49ers have not yet announced such a deal, but according to LaCanfora, Boone was given a $1.7 million signing bonus as part of the deal.
Boone was scheduled to become an exclusive rights free agent after this season. Keeping him inactive for much of last year basically bought the 49ers an extra season of Boone before this extension. As an ERFA, Boone would have not been able to negotiate with any other team in the offseason unless the 49ers let him. Instead, he is now signed through 2014.
Boone's new deal basically ripped up his 2011 contract and signed him through 2014. He will earn $450,000 in 2011, $540,000 in 2012, $950,000 in 2013 and $1.2 million in 2013. The deal reportedly includes some escalators as well that likely have to do with playing time.
Boone has established himself as the team's "swing" tackle, backing up both Joe Staley and Anthony Davis. There have been some comments here about moving him inside to the guard position, but it doesn't sound like that will be happening any time soon. With Staley signed through 2017 and Anthony Davis signed through 2014, this secures the edges of the 49ers offensive line for the foreseeable future. Of course, it will be interesting to see how the competition plays out between the three of them heading into 2012 training camp.
