The setback occurred during an “on-court rehab session” on Monday, according to the team statement.
Harden had an MRI on Tuesday and will remain out indefinitely.
“We’re back to square one,” head coach Steve Nash said, according to an ESPN report. “He will be back when he’s back. It might be the playoffs. It might be sooner.”
Over the weekend, GM Sean Marks expresses optimism that Harden would suit up soon, so this obviously caught the Nets by surprise. Harden suffered the injury in the early going against the Knicks on April 5.
If the injury continues to sideline him or be a source of concern during the postseason, it could obviously affect the team’s championship aspirations. Harden has played to an MVP level since forcing a trade from the Rockets in January. He’s averaging 25.4 PPG, 11.0 APG and 8.7 RPG with Brooklyn.
