Sixers coach Brett Brown said last week that he expected Simmons to return at some point this season but acknowledged that Colangelo and team management would make the final determination.
Simmons, who spent one season at LSU before opting for the National Basketball Association, broke his right foot at the end of September and has yet to play a regular-season game for the Sixers.
Ben Simmons will continue to just cheer on the 76ers from the bench as top pick is shut down for season.
Philadelphia 76ers rookie Ben Simmons will not play this season after tests revealed that his broken right foot has not fully healed. But there was always the outside chance that it didn't happen because there wasn't complete or full healing.
"The scan on his (Simmons) right foot the first overall pick had on Thursday at the Hospital of Special Surgery in NY showed that his foot still has not finally healed", Keith Pompey of Philly.com reported Friday.
Colangelo expressed that the team was hopeful Simmons would see game action this season, but believed that risking further injury was not worth it.

He is now being held at the Charleston County jail while he awaits a state trial on murder charges stemming from the attack. In December, a jury convicted Roof of 33 federal charges for killing nine Bible study goers in cold blood as they prayed.
"Unfortunately, Ben is going to sit out".
"There are genetic things that change the healing patterns of people", Colangelo said at the press conference.
Simmons underwent surgery to fix a broken bone in his right foot in October.
Simmons averaged 19.2 points, 11.8 rebounds, and 4.8 assists in his one season with LSU previous year.
Nerlens Noel and Joel Embiid also missed their whole first professional season with the 76ers.
