Just like Amar’e Stoudemire, who wasn’t insured by the New York Knicks to play in this summers world games, Team USA lost another big man Wednesday, as David Lee will miss the world championships because of an injured middle finger on his right hand.  USA Basketball said Lee will have his finger placed in a splint and could miss six weeks.  The All-Star forward is expected to be ready in time for the Golden State Warriors' training camp.  Lee was hurt Tuesday, the first day of practice. He flew to San Francisco and was examined by Dr. Bill Green, who diagnosed him with "mallet finger," an injury to the tendon.  Lee, who just signed a six-year, $80 million contract with the Warriors after averaging 20.3 points and 11.7 rebounds for the New York Knicks last season, was trying to earn a spot on the 12-player roster that will compete in Istanbul, Turkey, from Aug. 28 to Sept. 12.
