MINNEAPOLIS >> Minneapolis police are investigating a shooting inside a downtown nightclub that injured 9 people, including a Minnesota Vikings defensive tackle.

The team released a statement Saturday saying Linval Joseph was shot in the calf. He was treated for a minor injury and released. The Vikings described Joseph as an innocent bystander.

Police spokesman Scott Seroka says two people with serious injuries were in stable condition Saturday and expected to survive. He didn’t know the exact condition of the other seven but described most as having minor injuries.

Club owner Johann Sfaellos told the Star Tribune it was a typical night with patrons busy socializing and dancing, with no fights until he heard gunshots.

Police are still looking for the shooter. Seroka expected more information to be released Monday.
