Powell (shoulder) has been ruled out for Sunday's game against the 76ers, Adam Aaronson of PhillyVoice.com reports.
Powell was a late addition to the injury report Sunday morning due to right shoulder inflammation and soreness, and he'll miss his first game of the season. The veteran swingman's next chance to play will come Wednesday against the Spurs. Isaac Okoro will get the starting nod in Powell's stead. Additionally, Buddy Hield and Tre Jones could also see increased minutes.
