CLEVELAND — The Cavaliers wanted to use this summer to put their new backcourt of Kyrie Irving and Dion Waiters together early.

They didn't even make it to the first game.

Irving, the team's young star and the NBA's reigning rookie of the year, broke his right hand slapping a padded wall in practice on Saturday and is expected to miss two months.

"It just really alters all the plans we had this summer as far as summer league was concerned," Cavs coach Byron Scott told reporters in Las Vegas on Sunday before the team opened summer league play against Charlotte. "That was Plan A. We didn't have a Plan B going into this because you just never imagine that happening."
