But the Cavaliers point guard will return to the floor on Wednesday against the Magic, Mike Brown told reporters.
Irving injured his right bicep after Griffin landed on him with an elbow.
It's probably too late for the Cavs to make a serious playoff push, but they are at least still in the conversation and have something to play for. Entering Wednesday, they're three back in the loss column to the slumping Hawks, and two games behind the Knicks. With only seven games remaining, it seems unlikely, but who knows.
Irving, 21, is averaging 21.5 points and 6.3 assists this season.
