Michael Rubin -- the billionaire minority owner of the Philadelphia 76ers -- is selling his stake in the Harris Blitzer Sports Entertainment company which owns the Sixers and the New Jersey Devils.
Rubin, 49, shared the news this week during an interview with FOX Sports ... saying he decided to unload the teams after 11 years of ownership because of a conflict of interest.
The conflict? Michael's the CEO of Fanatics, and the company is getting involved in the incredibly lucrative sports gambling industry.
