Cleveland Cavaliers star Kyrie Irving will miss the remainder of the NBA Finals with a fractured left kneecap, but LeBron James vows his team will be ready for game two Sunday. Irving, who collapsed in over-time of Cleveland's 108-100 loss to Golden State in Thursday's opener, will undergo surgery in the next few days and the 23-year-old All-Star guard is expected to need three or four months to recover. Losing Irving, who averaged 18.7 points and 3.7 assists in the playoffs and 21.7 points and 5.2 assists this season, is a major blow for a team that already star big man Kevin Love in the opening round with a separated shoulder.
