LeBron James isn't sure if he wants to play in the Olympic Qualifying Tournament this summer in Las Vegas.

Jerry Colangelo has said he expects the players to honor the promise or risk being left off the Olympic roster.

``Unless people have a legitimate reason for not participating, I expect them to uphold their three-year commitment,'' Colangelo told ESPN.com. ``If someone chooses not to participate just because they'd rather not play, that person would put himself at risk as far as who ultimately represents us at the Olympics.''

Last week in front of the New York media, James updated his thoughts on the summer: ``Right now, I'm 50-50. My girlfriend is expecting another [baby] in June. Health is always an issue. You have to re-evaluate things, go through the season, go through the playoffs and then look at it afterward.''
