BOSTON (AP) LeBron James responded Sunday to USA Basketball chairman Jerry Colangelo's warnings about skipping the world championships, saying he has already proven his commitment to the team.

Colangelo said Wednesday any player who sat out this summer without a good reason was jeopardizing his chances of playing in the 2012 Olympics in London, saying there are "no free passes, regardless who it is." Dwyane Wade also has hedged about taking part.

Asked about the comments Sunday, James said: "I think everyone in the USA knows what type of commitment these guys have made, including myself, since 2003," James told reporters before the Cavaliers' 117-113 loss in Boston.
