Couturier underwent back revision surgery Thursday and is expected to be out 3-4 months, Jordan Hall of NBC Sports Philadelphia reports.

This is a big setback for the center, who hasn't played since Dec. 18, 2021 due to back woes. Couturier's scheduled to return at some point in February, barring any more setbacks.
