Andre Iguodala has taken over as the acting executive director of the National Basketball Players Association after the resignation of Tamika Tremaglio, as announced by the union on Thursday. Tremaglio stepped down from the position to pursue new opportunities, and Iguodala’s appointment has been approved by the NBPA’s executive committee.

Tremaglio had not completed two full years into her four-year term as executive director, and it was not immediately clear if Iguodala, a four-time NBA champion who retired after last season and had been a longtime union officer, would be interested in the job on a permanent basis.

The change at the top of the union seemed to come as a surprise, given that Tremaglio had just met with the Indiana Pacers and had plans to attend the All-Star weekend in February. “I am honored to take on this role and serve the players, who are the heart and soul of the NBA,” Iguodala said in a release distributed by the union.

While the NBA and the NBPA are in constant communication about various matters, the biggest issue that the sides deal with is not expected to be a major topic for several years. The league and its players are still in the opening months of a new Collective Bargaining Agreement.

“His leadership on the NBPA Executive Committee was imperative to multiple rounds of CBA negotiations, and he has empowered our players to think like the business titans they are,” Tremaglio wrote of Iguodala on social media last month.
