Jodie Meeks has been suspended 25 games by the NFL for violating the NBA/NBPA Anti-Drug Program.
Meeks tested positive for banned compounds Ipamorelin and Growth Hormone Releasing Peptide-2.
Meeks' season with the Wizards is now over.
When reached Friday by ESPN, Meeks' lawyer Ben Levine of Gordon Rees Scully Mansukhani said: "It is regrettable that the NBA has prematurely taken action against Jodie today. Accordingly, we will appeal the suspension and vigorously defend Jodie's rights. Unfortunately, under the CBA, a player is guilty until proven innocent and while Jodie's appeal is pending he will be forced to sit out the playoffs."
