Wheeler became a free agent Saturday after his 10-day contract with the 76ers expired, Adam Aaronson of PhillyVoice.com reports.
Wheeler averaged 1.6 points and 1.6 rebounds in 8.8 minutes across his five appearances for Philadelphia. Before being signed to a 10-day deal with Philadelphia, Wheeler had been playing for the G League's Maine Celtics, so he could rejoin the club for its postseason run.
