"I'm in," James said Sunday.
The game is perhaps the biggest yet in a series of summer exhibitions featuring players who are waiting for the NBA lockout to end. Durant has been at the center of many of those matchups, scoring 66 points one night at New York's famed Rucker Park and later leading Washington's Goodman League to a 135-134 victory over the Drew League from Los Angeles.
James, Paul and Anthony are all scheduled to be on the same team Tuesday.
Anthony is a Baltimore native, and proceeds from ticket sales will go to charities that the New York Knicks star is involved with.
