Waiters has had issues with the left ankle for a while, and he's missed the last nine games after he turned the ankle in the first quarter of Miami's game against the Mavericks on December 22. Waiters reportedly sought several opinions on his ankle.
He missed 13 games last season due to a sprain of the same ankle, but ultimately opted to decline surgery, as he was entering free agency, where he ended up signing a four-year, $52 million deal with the Heat.
It's unclear what changed leading to the surgery announcement, but it's a major loss for Miami, which now sits fourth in the Eastern Conference with a 24-17 record.
Waiters this season is averaging 14.3 points and 3.8 assists per game, shooting just 39.8% from the field and just 30.6% from three-point range. Johnson played against the Pacers but came off the bench and scored 15 points.
