Philadelphia 76ers' Joel Embiid comes out in a "Phantom of the Opera" mask as he rings a Liberty Bell replica before Game 1 of the team's first-round NBA basketball playoff series against the Miami Heat, Saturday, April 14, 2018, in Philadelphia.
Embiid averaged 22.9 points, 11 rebounds, and 3.2 assists during 63 regular season games.
ESPN's Ramona Shelburne reported that all Embiid had to do to clear concussion protocol was prove he could withstand contact.
Reserve swingman Timothe Luwawu-Cabarrot will also miss Monday's game with right knee patellar tendinitis.
Warm Friday with rain heading this way
Breezy, with a north wind 10 to 15 miles per hour increasing to 19 to 24 miles per hour in the afternoon. Temperatures in Grand Forks will be in the mid-30s to the upper teens throughout the weekend.
Without Embiid, the Sixers dominated the Heat in Game 1.
Joel Embiid's return will have to wait until Friday (AEST) at the earliest. That game will be 8 p.m. Monday at the Wells Fargo Center.
He sat out the team's 130-103 routing of the Heat on Sunday but could return for Game 3 in Miami later this week. "And to have him come back and save the day because we lost Game 1, that's not going to happen".
Delon Wright and CJ Miles each had big games off the bench, combining for 30 points for the top-seeded Raptors, who snapped a streak of 10 straight Game 1 losses. And I feel great.
The Sixers, who set an National Basketball Association record with 16 straight wins to end the season, got the rout in full swing with a raucous crowd behind them.
