Anthony Barr was at the Vikings facility last weekend, alongside some teammates lending a helping hand at Mike Zimmer’s youth football camp.

However, Barr did not show up Tuesday when the Vikings began the first of 10 voluntary practices, known in the as NFL world Organized Team Activities.

“He came to me [Tuesday] and said he wasn’t going to be here,” Zimmer said Wednesday following the Vikings’ second OTA.

Barr, 26, is one of a few cornerstone Vikings entering the final year of his contract. When asked if Barr’s absence was related to his contract status, Zimmer declined to elaborate.

“I don’t worry about those things,” Zimmer said. “I just know the conversation we had, I’ll keep between myself and him.”

Barr is due a fully-guaranteed $12.306 million base salary, coming via a fifth-year option on his rookie contract. The Vikings drafted Barr with the ninth-overall pick in 2014. He has since been named to three consecutive Pro Bowls.
