The Philadelphia Sixers have been granted permission from three separate teams to interview their current executives for their vacant general manager job, according to ESPN’s Adrian Wojnarowski.

According to sources, the teams ownership group will meet with Golden State's Larry Harris, Houston's Gersson Rosas and Utah's Justin Zanik next week.

Harris was the Bucks GM from 2003-2008, and since 2015 he has been the assistant GM of the Golden State Warriors.  Rosas has been a longtime a member of the Houston Rockets front-office and is currently the Executive Vice-President of Basketball Operations.  Zanik has been both an agent and executive, working with both the Bucks and Jazz.

The Sixers have been operating with Brett Brown as the interim GM since they fired Bryan Colangelo back in June. Ned Cohen, Marc Eversley and Elton Brand are the other front-office executives that have assisted Brown and been elevated this summer.

Sixers managing partner Josh Harris told ESPN.com earlier this week that he wouldn't rule out leaving the interim structure in place for the 2018-19 season.

"There are a very small number of elite sitting GMs and they're generally under contract with teams for a long time," Harris told ESPN on Monday. "Those situations tend not to change much. For us, we need someone to add real value, which includes looking at young, up-and-coming basketball executives and non-traditional candidates.

"We're going to have a pretty selective list," Harris said. "This is not going to be huge tournament. We're going to talk to some people who aren't sitting GMs who could add value to our situation."
