Mark Tatum to become NBA deputy commissioner

Mark Tatum will become the NBA's deputy commissioner when Adam Silver succeeds David Stern on Saturday.

NBA owners have unanimously approved the appointment of Tatum, a 15-year veteran of the league office, and he will also be the chief operations officer.

"Mark will use his extensive industry relationships and knowledge of our game to help guide and grow our league," Silver said, ESPN reports.

Silver has been deputy commissioner since 2006, and he will be promoted as Stern retires after 30 years.
