76ers superstar center Joel Embiid is currently listed as out for Game 3 of Philadelphia’s Eastern Conference semifinal against the MiamI Heat, but there is progress that could be made to change his availability in time to play Friday, sources told ESPN’s Adrian Wojnarowski. As 76ers coach Doc Rivers said Thursday afternoon, Embiid has yet to be cleared from the NBA’s concussion protocol. He can only be listed as out until he does.
