Embiid was trying to make a defensive play 12 seconds before halftime of a 121-107 loss to Indiana. He did not return to the game and will undergo further evaluation this weekend.

Sixers guard Jared McCain also suffered an apparent head injury when he hit his head on the floor during the second half on Friday, but he cleared the NBA’s concussion protocol and was able to return to the game, via Kyle Neubeck of PHLY Sports.

30 minutes before the start of the game, the Sixers added veteran point guard Kyle Lowry to their injury report as questionable with lower back spasms. Moments later, he was ruled out for the game. Nurse has noted in the past a desire to be cautious with the workload of Lowry, the 38-year-old floor general with plenty of mileage.
