The San Francisco 49ers agreed to terms on a 2-year contract extension with left tackle Joe Staley. We break down what it might mean for the 49ers current holdouts, Alex Boone and Vernon Davis.

The San Francisco 49ers find themselves a little bit busy today. After cutting the ribbon to officially open Levi's Stadium, and then placing eight players on the NFI and PUP lists, the 49ers announced they have signed left tackle Joe Staley to a 2-year extension. The deal will keep him in San Francisco through 2019. He turns 35 prior to that season, which means he very well could finish up his career with the 49ers.

There are no contract details, but with a couple extra years added on, the 49ers could give him a nice little signing bonus to pro-rate over the life of the deal. Conceivably it could get Staley a raise while creating some cap space now. Staley is generally considered one of the better bargains among NFL offensive linemen, in part because he signed a big extension early before he really had fully established himself. We saw that he was going in the right direction, but it has been during the life of this extension that he has really come into his own.
