Daniel Theis won't jeopardize a long-term reward for a short-term risk.
The Celtics center revealed he'll miss Boston's preseason opener Tuesday night against the Philadelphia 76ers due to a sore back. The Celtics initially listed Theis as questionable.
"It's early, so there's no reason to risk anything," Theis said, per the Celtics. "Just take it day-by-day."
The Celtics will tip off their regular season Dec. 23 against the Bucks. It's unclear whether center Tristan Thompson will recover from a hamstring injury in time to face Milwaukee, so it's even more important for Theis to be as close to 100 percent healthy as possible in just over one week's time.
