New York Knicks center Joakim Noah will be suspended 20 games for violating the NBA's anti-drug policy, a suspension that will start once he is healthy and able to play.

More details on the suspension, via USA Today:

The 32-year-old tested positive for an over-the-counter supplement, selective androgen receptor modulator LGD-4033, that is banned under the collective-bargaining agreement. Noah had arthroscopic surgery on his left knee Feb. 27, but he has not played since Feb. 4. He wasn't expected to return to the Knicks' lineup this season. The suspension will begin the first game he is “eligible and physically able to play,” according to the NBA's release.

The suspension will cost him nearly $2.5 million in salary.

According to a selective androgen receptor modulator site, LGD-4033 is non-steroidal supplement for enhancing lean muscle and reducing fat.

The suspension might not affect Noah and the Knicks until next season with just a few games remaining this season.

In the summer, the Knicks signed Noah to a four-year, $72 million contract. In 46 games this season, Noah averaged 5.0 points and 8.7 rebounds.
