The Sixers have set no timeline in which to name a general manager. Thorn has a little less than one year remaining on his contract. Upon its completion, Thorn will move to an advisory position with the Sixers.
Meanwhile, according to a league source with knowledge of the situation, one of the three candidates mentioned for the job - Boston assistant general manager Mike Zarren - has withdrawn his candidacy. The Sixers have also interviewed ESPN analyst and ex-Portland Trail Blazers assistant general manager Tom Penn, whom they have cooled on, according to a source, and former New Orleans general manager Jeff Bower.
DiLeo was a finalist earlier this summer for the Portland general manager's job, which went to former Los Angeles Clippers general manager Neil Olshey.
DiLeo has been a part of the Sixers basketball operations department since the 1990-91 season. Most recently, before assuming his current position with the club, DiLeo took over for fired coach Maurice Cheeks after the Sixers began the 2008-09 season 9-14.
The Sixers went 32-27 the rest of the way and reached the playoffs as the sixth seed. DiLeo returned to the front office before the start of the 2009-10 season.
The Sixers begin training camp Oct. 2 at St. Joseph's University. They open their preseason schedule Oct. 11 in Orlando, and they open the regular season against Denver at the Wells Fargo Center on Oct. 31.
