Union chief Michael Weiner says he expects Jay-Z and two other Roc Nation Sports executives to ask the Major League Baseball Players Association to grant them permanent certification to represent players in contract negotiations with clubs.

“We’re told we will receive their applications, but we have not received them yet,” Weiner told the Daily News on Wednesday.

The hip-hop star’s tiny ownership interest in the Nets could be a hurdle, and Jay-Z might have to sell his stake in the NBA team in order to receive permanent certification. MLBPA rules bar anyone with a conflict of interest, such as an ownership stake in a major league team, from representing players. An ownership stake in an NBA team, however, isn’t specifically prohibited.

“We have rules about conflicts of interest,” Weiner said. “We’ll examine if there will be a conflict on the management side after we receive the application.”
