Cooper Flagg sustains mild shoulder sprain in win over Pacers after taking hard foul from Aaron Nesmith

Cooper Flagg suffered a mild left shoulder sprain during a 121-105 win over the Indiana Pacers on Friday, the Dallas Mavericks announced Saturday .

Flagg will be out for the Mavs' Saturday night home opener against the San Antonio Spurs and will be re-evaluated next week, per the team's announcement.

Flagg left Friday's game in the second quarter and didn't return. He went down after a hard foul from Pacers forward Aaron Nesmith, who appeared to hit Flagg in the back of the head and caused the Mavericks forward to land awkwardly.

The incident sparked a heated argument between Nesmith and Mavericks forward Naji Marshall, with Nesmith having to be separated from the group.

Nesmith was called for a flagrant foul after the contact, while both Nesmith and Marshall were given technical fouls for the incident.

Flagg hit both of his free throws awarded after Nesmith's flagrant, which occurred in the final minute of the half. He was subbed out afterward and headed into the locker room before halftime, grabbing at his left shoulder.

At the time he left, Flagg had racked up 14 points for the Mavericks in 17 minutes of play.

The Mavericks went on to get the 16-point victory over the Pacers behind 24 points from Kyrie Irving. Dallas led by as many as 37 points in the win.
