Vikings' Brian Robison: Signs extension through 2018

Robison signed a one-year extension that takes his contract through 2018, ESPN's Field Yates reports.

Analysis:

Robison agreed to reduce his 2017 base salary from a non-guaranteed $5.3 million to a fully-guaranteed $3.9 million, with the number then dropping to $3.2 million (including $1.25 million guaranteed) for 2018. He'll turn 34 in April and has never recorded double-digit sacks in a season, but his run defense and consistency have long made him an asset to the Vikings. Robison has played 15 or 16 games in each of his 10 NFL seasons, recording 4.5 or more sacks each of the past six years while starting every contest he's played.
