Johnson played 33 minutes in Wednesday night’s game against the Celtics and didn’t seem to suffer an injury, so this could be generic wear and tear. That being said, missing Johnson, who has emerged as a legit star this season, would be a big loss for the Hawks. Corey Kispert and Luke Kennard would likely see more minutes, with Nickiel Alexander-Walker and Dyson Daniels getting an uptick in usage.
