The Cavaliers said both players - the No. 1 picks in the last two NBA drafts - would warm up and were dressed, but that both had already given the team all it needed to see in four previous games in Las Vegas.
Friday's game was the summer finale for both the Cavaliers and Heat. Wiggins averaged 15.5 points and Bennett averaged 13.3.
Several outlets reported Thursday that the Cavaliers had decided to make Wiggins available in trade talks with Minnesota for Kevin Love. But two people familiar with the situation told The Associated Press that the Cavaliers' position has remained unchanged and that no offer including Wiggins has been made. The people requested anonymity because neither team was publicly commenting on trade talks.
