Adrian Wojnarowski: Memphis guard Nick Calathes will be suspended 20 games for violation of NBA's Anti-Drug policy.
Calathes tested positive for Tamoxifen, which was in an over-the-counter athletic supplement he had used.
The NBA's lab results showed no traces of testosterone or PED in supplement, source says. "There was no intent here," says league sources.
Calathes has been important part of Grizzlies backcourt rotation and his 20 game suspension will begin immediately.
This is going to hurt the Grizzles. Looks like Beno is going to have to step up in the backup role behind Conley.
