"We're back to square one," Nets head coach Steve Nash told reporters ahead of Tuesday's game at the New Orleans Pelicans, per an ESPN story.
"He will be back when he's back. It might be the playoffs. It might be sooner."
The NBA Playoffs are currently scheduled to begin May 22, and the Nets won't need Harden to qualify for the tournament. Brooklyn began Tuesday evening second in the Eastern Conference standings at 38-19, one game behind the Philadelphia 76ers.
Harden was averaging 25.2 points, 10.9 assists, and 8.0 rebounds per game before he logged just four minutes against the Knicks. According to Matt Eppers of USA Today, the trio of Harden, Kevin Durant, and Kyrie Irving has played only seven games together since Harden joined Brooklyn in January.
