Okafor, 36, signed a non-guaranteed deal for the veteran’s minimum shortly before training camp opened last month. He had been hoping to win a spot as a backup to Joel Embiid and a veteran leader on one of the NBA’s top teams.
Okafor completed a remarkable comeback story when he earned a roster spot with the Pelicans in February after signing a pair of 10-day contracts. It marked his return to the league after missing four seasons because of injury. He appeared in 26 games, starting 19, and averaged 4.4 points and 4.6 rebounds per night. However, he barely played in the postseason.
New Orleans waived Okafor last month and he signed with the Sixers two days later.
Jefferson and Johnson signed with Philadelphia yesterday and both appear headed for the G League.
