The 76ers stormed home in the second half, outscoring the Heat 74-43 without star Joel Embiid, who is recovering from a fractured orbital bone.
Embiid had surgery on March 31.
Ben Simmons narrowly missed a triple-double, and the Philadelphia 76ers punished the visiting Miami Heat from long range en route to an easy 130-103 victory Saturday in an Eastern Conference first round series opener.
Belinelli scored 25 with four 3s; Ilyasova went for 17 points and 14 rebounds and was the catalyst as Philly started taking over the game, Dario Saric chipped in 20 points and four 3s of his own, and Simmons went for 17 points, 14 assists and nine rebounds while getting his first taste of the postseason.More news: Accusers confront Bill Cosby, and they aren't holding back
According to ESPN's Ramona Shelburne, Embiid passed the NBA's concussion protocol, but remains out.
Additionally, guard Timothe Luwawu-Cabarrot will sit out the game with patellar tendinitis in his right knee.
Without Embiid, the Sixers dominated the Heat in Game 1. The timetable for return was 2-to-4 weeks.
Coach Brett Brown shrugged when asked if Embiid's return, or lack thereof is linked to the success the Sixers have had without them. He will not play in Game 1 and from that point going forward, we'll figure some stuff out. And I feel great. The club is 9-0 without its All-Star center, who averaged 22.9 points, 11.0 rebounds and 1.8 blocks in 63 games in the regular season. That game will be 8 p.m. Monday at the Wells Fargo Center.
