Reaves exited Wednesday's game against the Bucks with an undisclosed injury, Khobi Price of The California Post reports.
Reaves came up lame after a drive to the hoop, subbed himself out of the game, and limped back to the locker room. For now, he should be considered questionable to return, and if he needs to miss time, that will open up minutes for Ziaire Williams and Collin Sexton.
