ESPN reports: “Section 5(B)(5)(a) of the Players Association regulations states: “No Player Agent or Applicant shall provide, cause to be provided or promise to provide, any money or any other thing of value to any player, or any person related to or associated with such player, the purpose of which is to induce or encourage such player to use or continue to use any person’s or firm’s services as a Player Agent, Representative, or Draft Advisor.”
There is a clause allowing certain gifts if the player was already a client of the agent; however, any gift exceeding $500 must be disclosed to the union in writing. Players Association officials say the seven paragraphs of rules are meant to ensure that players choose their representatives on merit rather than what the union calls “improper inducements.”
Sources said that the Players Association has interviewed several of the principals and that Jay Z could be subject to unspecified discipline if he is found in violation.”
