Minnesota Vikings re-sign Brian Robison

The Minnesota Vikings took a step Thursday to shore up their defensive line by signing defensive Brian Robison to a three-year deal worth $14.1 million, according to the Star Tribune's Chip Scoggins.

Robison was scheduled to be a free agent this offseason, but now will likely start next season as the team's right defensive end. Ray Edwards, the Vikings starter at the position last season, is a free agent and expected to sign elsewhere.

Robison, who turns 28 next month, has 13.5 sacks during his four-year NFL career. The deal also includes a $6.5 million signing bonus.
