Giddey (hamstring) has been ruled out for Sunday's game against the Heat.
Giddey will miss a third consecutive game while managing a left hamstring injury, and his next chance to play is Tuesday against the Bucks. The Bulls will get Coby White (calf) back for Sunday's tilt, while Ayo Dosunmu and Isaac Okoro should continue to see expanded roles on offense in Giddey's absence.
