While visiting a Tribune property in Denver this week, Zell said Tribune will "in all likelihood" keep some kind of minority interest in the Cubs.
He didn't specify what percentage interest Tribune might keep, but made clear his interest in letting a new owner take control and said the Cubs belong in entrepreneurial hands.
Zell says nine potential buyers have been preapproved by Major League Baseball and are awaiting release of the team's financial data, which should be sent out soon.
