The knee injury that limited linebacker Anthony Barr to one practice over the past month will keep him out of the Vikings' regular-season opener on Sunday in Cincinnati.
Barr has been ruled out against the Bengals after missing the past two days of practice. He had returned to practice Wednesday, and was listed as a limited participant, but he felt sore on Thursday morning, according to coach Mike Zimmer, and sat out the rest of the week.
Even with Barr's inability to practice, Zimmer pushed back when asked if the team is considering shelving the Pro Bowler for longer than this week.
"He's close," Zimmer said Friday, "so we'll just see."
The Vikings will turn to linebacker Nick Vigil, the former Bengals and Chargers defender who signed a one-year deal in free agency, to replace Barr as an every-down player next to Eric Kendricks. Vigil will also wear the in-helmet microphone and relay defensive play calls to the huddle, which is typically Barr's responsibility.
Vigil's four years with the Bengals, where he played in a similar defensive scheme and also relayed the calls, are expected to help him in his return to Paul Brown Stadium.
"For two or three years in Cincinnati, I had the green dot," Vigil said. "I'm pretty familiar with it. Last year, I didn't, but I've called plays before and done it before."
The Vikings will also need a third defender to take Barr's spot as the strong-side linebacker in the base defense, where Blake Lynch has served as his backup. But Ryan Connelly or Troy Dye could also see some playing time. Vigil, the most experienced among them, will shoulder the most in Barr's absence.
