Center Nerlens Noel still owes super agent Rich Paul for his Knicks’ contract, according to a grievance filed by his former rep.

According to sources, Paul recently filed a grievance to the Players Association that Noel owes him $200,000 as commission for the one-year, $5 million deal he signed with the Knicks during last November’s free agency.

Industry sources believe Paul’s grievance may have been the impetus in Noel filing a $58 million lawsuit against Paul on Tuesday, claiming Paul was negligent in representing him.

Noel fired Paul soon after signing with the Knicks and did not pay his bill, the grievance states.

Noel’s lawsuit claims Paul advised him in 2017 against signing a $70 million extension with the Mavericks as he lured him away from former agent Happy Walters. Noel’s lawsuit also states he didn’t get back to various teams who inquired about his availability.

Noel took full advantage of his Knicks opportunity this past season as a shotblocking specialist, and started when Mitchell Robinson went down with two serious injuries.

Noel parlayed that into a three-year deal that could be worth up to $32 million with bonuses, signed earlier this month with his new agent, George Langberg.
