The 23-year-old's preseason finale against the Atlanta Hawks was cut short when he walked to the locker room. After two days, Thunder head coach Mark Daigneault said he is day to day with the ankle sprain. Williams was spotted at the Thunder's practice. He worked on mostly catch-and-shoot 3-pointers from what the media observed.

Hours later, rising star forward Jalen Williams rolled his ankle in the second quarter and immediately exited the game. The injury was categorized as a left ankle sprain, although no recovery timetable was announced. The 23-year-old was evaluated on Friday morning.
