Prior to the setback, Harden was expected to return soon from the injury, which has forced him to miss eight games in April.
“We’re back to square one,” coach Steve Nash said before Tuesday’s game vs. the New Orleans Pelicans. “He will be back when he’s back. It might be the playoffs. It might be sooner.”
The nine-time All-Star averaged 25.4 points, 11.0 assists and 8.7 rebounds over his first 34 games with Brooklyn.
The Nets (38-19) are currently the 2nd seed in the Eastern Conference standings.
