Bjelica never actually signed his contract with Philadelphia, sources told Wojnarowski.
Bjelica, 30, spent the past three seasons with the Minnesota Timberwolves, who recently rescinded his qualifying offer to make the Serbian forward an unrestricted free agent.
The Sixers had intended to use their $4.4 million midlevel exception to sign him.
Bjelica, who shot 41.5 percent on 3-pointers and averaged 6.8 points per game this past season, was the EuroLeague MVP in 2015 prior to joining the NBA.
