David Blatt has said that Kyrie Irving is still not 100% recovered from a knee problem that hampered him during the Eastern Conference finals.
The point guard missed two of their four games against the Atlanta Hawks after struggling with knee tendinitis.
The Cleveland Plain Dealer reports the coach as saying that Irving, who has been taking part in some of the team's practices, is "still not himself yet".
The Cavaliers face the Golden State Warriors in the NBA Finals from Thursday.
