An agreement between Kyle Lowry and the Toronto Raptors is "imminent", according to a source.
Teams, however, cannot speak to free agents from other clubs until after July 1.
"Lowry will be a member of the Heat," said the source, regardless of how the discussions between the current Big about opting out progress.
The Heat would like to transform its Big Three of LeBron James, Dwyane Wade and Chris Bosh into a Big Four that includes Lowry and Carmelo Anthony instead of Bosh.
