7:55pm: Sixers spokesperson Michael Preston told Bob Cooney of the Daily News (on Twitter) that Aron has not been fired.
4:26pm: The Sixers have fired CEO Adam Aron, sources confirmed to Dei Lynam of CSNPhilly.com (via Twitter). It was rumored back in May that Aron was taken out of the basketball side of things but that was denied by a league source at the time. The move was first reported by Howard Eskin of WIP (on Twitter).
Last month, John Nash said in an interview that Aron had his role reduced after a clash with consultant and former coach Doug Collins. It's unclear if Aron's dismissal has anything to do with that rumored tiff or if it could be tied to the arrival of new GM Sam Hinkie. There has been quite a bit of change in Philly recently with both Collins and former team president Rod Thorn transitioning into advisory roles.
