A source familiar with the process told the Sun Sentinel that the Miami Heat were in the process Tuesday of setting up a meeting with LeBron James amid the forward's free agency, with word from James' camp that the summit would be Wednesday.

   Pat Riley and his staff traveled to Las Vegas for the meeting, with James holding a basketball camp there.

   Heat guard Dwyane Wade, who also is a free agent, also is in Las Vegas, with Yahoo Sports reporting he dined Monday night with James.

   There were mixed signals Tuesday about whether Wednesday's meeting would lead to an immediate announcement, with some parties involved believing further deliberations from James could ensue.

  While James has maintained a low-key presence since the July 1 start of free agency, Riley has attempted to bolster the Heat with the free-agency additions of forwards Josh McRoberts and Danny Granger.

   While the free-agency negotiating period opened July 1, free-agent contracts cannot be signed until Thursday, at the end of the NBA's annual summer personnel moratorium.

   James' agent, Cleveland-based Rich Paul, already has taken meetings with potential James suitors, including the Los Angeles Lakers, Phoenix Suns, Houston Rockets, Dallas Mavericks and Cleveland Cavaliers.

   The Heat have advanced to the NBA Finals in each of the four seasons since James joined the team as a free agent in July 2010, winning consecutive championships, the first of James' career, before falling 4-1 to the San Antonio Spurs last month in the 2014 NBA Finals.
