Joakim Noah will not appeal his 20-game suspension for violating the league's anti-drug policy, he told reporters on Tuesday.
Noah, who has been medically cleared by the Knicks to practice, can begin serving his suspension once he is cleared by the NBA.
He said the substance that resulted in the suspension was not approved by the Knicks' medical staff and that he took it while rehabbing from an injury.
The Knicks hope Noah can be cleared by Wednesday's game against the Miami Heat, according to ESPN's Ian Begley, meaning he would serve eight games of the suspension this season.
Noah, 32, has averaged 5.0 points and 8.8 rebounds in 46 games this season while missing time due to knee, hamstring, and ankle injuries.
He signed a four-year deal with the Knicks worth $72.59 million prior to this season.
