Celtics' Luka Garza: Upgraded to probable

Garza (concussion) is probable for Sunday's game against the Pistons, Jay King of The Athletic reports.

Garza missed Friday's game against the Knicks while in concussion protocol but appears on track to return Sunday. He's unlikely to see heavy minutes, though the center rotation among him, Neemias Queta and Xavier Tillman is far from settled.
