Both teams are playing their final regular-season game. The teams will participate in the playoffs, which begin this weekend.
The Cavaliers have won five consecutive regular-season meetings. This season they've beaten the Hawks twice at home and once at Philips Arena.
The Cavaliers also swept the Hawks 4-0 in the 2009 Eastern Conference semifinals.
Shaquille O'Neal has been cleared to play for the Cavaliers. He has been out since Feb. 25 because of a thumb surgery.
Cleveland coach Mike Brown has yet to decide if All-Star forward LeBron James will play. He has sat out the past three games because Cleveland already has clinched homecourt advantage throughout the playoffs.
Jamal Crawford (toe) is questionable, and Jason Collins (foot) is probable for the Hawks.
