Dwyane Wade is expected to play after a sore knee caused him to miss Monday’s practice and Tuesday morning’s shootaround.
LeBron James, who has a sprained left ankle, also missed the morning workout and will be a game-time decision. James said Monday he had some improvement after being a late scratch against the Bulls and hoped to be cleared by team trainers to play against the Hawks.
Chris Bosh, however, will miss the game with a sprained left ankle suffered against the Bulls. Heat coach Erik Spoelstra did not name a starter to replace Bosh as the team is already without backup Udonis Haslem. It will likely be between Juwan Howard and Joel Anthony.
The Hawks have won six of their last seven games and bring a four-game road winning streak to Miami.
