Second-year center Nik Vucevic and rookie point guard Zack Rosen, the Ivy League player of the year from Penn, were among the players who did not participate in the Sixers' loss.
Vucevic did not play because of an aggravated Achilles tendon and will be day-to-day in the summer league, according to McKie.
"He should be able to play, but I'm not 100 percent sure," the coach said. "I'm hoping that's the case. I have to check with our medical staff. I don't know as of now."
The Sixers' next game will be Tuesday at 11 a.m. against the Utah Jazz.
Play of the day. Rookie forward Maurice Harkless, who was taken 15th overall in the draft, had a slow start for the Sixers but showed a glimpse of his potential when he drew contact, regained his balance, and softly placed the ball off the backboard for a layup in the final seconds of the first half. He finished with nine points and five rebounds.
Upside. Forward Justin Holiday, 23, a rookie out of Washington and Jrue Holiday's older brother, collected 10 points, seven rebounds, and two steals. He was the only Sixer who finished with a positive plus/minus rating.
Downside. The Sixers struggled offensively from start to finish, shooting 31.3 percent from the field.
Quotable. Harkless, on adjusting to the pro game: "It's definitely a lot more physical and guys are a lot stronger. Over time, that's something I'll be able to help myself [with] in the weight room and everything."
