The Minnesota Vikings have agreed to terms on a three-year deal worth $14.1 million with DE Brian Robison, FOXSports.com has learned. The deal includes a $6.5 million signing bonus and averages $4.7 million per season. Robison was on the final year of his rookie deal.

Robison, who was selected in the fourth round of the 2007 NFL Draft by the Vikings, earned $550,000 in base salary last season.

Robison, who has started seven games during his four seasons of play, participated in roughly 32 percent of the defensive plays last season. He also participated on special teams coverage.

With Robison coming back for another season, that could end DE Ray Edwards’ five-year tenure with the team. Edwards is unsigned for next season, but got a first-round restricted free agent tender from the Vikings. However, he could become an unrestricted free agent once the new CBA is completed and if it reverts to the old rules.

He now goes from primarily as a nickel pass rusher to a likely full-time starter assuming Edwards doesn't return.
