The Magic were concerned about this result being a possibility after the game, Marc Spears of ESPN reported, and an MRI has since confirmed the severity of the injury.
Isaac will be out indefinitely and his return to the court will “depend on how he responds to treatment and rehabilitation,” according to the Magic.
The injury occurred just minutes into the fourth quarter when Isaac drove to the basket, planted his left leg and fell to the ground in obvious distress. He had to be helped off the court with a wheelchair.
At the time he got hurt, Isaac had four points and three rebounds in the game.
Back in January, he suffered a hyperextended left knee that would have forced him to miss the entirety of the season if it had not been postponed due to the novel coronavirus pandemic.
The 22-year-old averaged 12.1 points and 6.9 rebounds per game this season, his third in the league.
