Orlando Magic forward Franz Wagner has a high left-ankle sprain that's expected to sideline him for multiple weeks, ESPN's Shams Charania reports. 

The injury projects to sideline Wagner for the remainder of NBA Cup play. Orlando will play the Miami Heat in the quarterfinals Tuesday night. The championship final is scheduled for next Tuesday in Las Vegas. 

The good news for Wagner is that he avoided more significant structural damage after a scary fall against the Knicks on Sunday, according to the report. Wagner fell to the court after a hard foul by New York's Ariel Hukporti.

Wagner immediately grabbed his lower left leg and rolled around on the floor in pain. He eventually needed the help of teammates to limp off the court.
