The National Basketball Players Association has filed a countersuit against Billy Hunter seeking "millions of dollars."

The NBPA alleges Hunter committed "willful and deliberate misconduct and breach of his fiduciary duties."

Hunter has been seeking at least $10.5 million in damages for alleged breach of contract.

"Hunter knowingly, intentionally, and willfully failed to secure the constitutionally required approval of the 2010 Alleged Contract in order to shield such contract from scrutiny by the NBPA's highest policymaking bodies and to thereby obtain the most favorable terms and conditions of employment for his personal benefit and to the detriment of the NBPA and its membership," the union alleges in the countersuit.
