Minnesota Vikings defensive tackle Linval Joseph was shot in the calf by a stray bullet fired in a Minneapolis nightclub Saturday morning.

The Vikings said in a statement that Joseph was an innocent bystander in the incident, which occurred inside 400 Soundbar minutes before closing time.

Joseph's injury is minor and he is expected to return to practice sometime next week. He was treated at a hospital and released Saturday.

The Minneapolis Star Tribune reported that police are looking for a gunman who shot multiple people inside the club.

"The entire Vikings organization is extremely thankful that Linval was not seriously hurt, and our thoughts are with all of the victims of this shooting," the team said in a statement. "The team will defer any further comment to the Minneapolis Police Department during its ongoing investigation."

The Vikings beat the Oakland Raiders 10-6 in a home exhibition game Friday night.

Joseph is in his first year with the Vikings. He spent the first four seasons of his NFL career with the New York Giants.
