MIAMI -- Jimmy Butler's debut for the Miami Heat will be delayed by a few days.

Butler was ruled out of Miami's season opener against Memphis on Wednesday for what the team is calling "personal reasons.''

Butler was with the Heat Wednesday morning for their game-day shootaround and told the team around midafternoon that he wasn't going to be able to play.

Heat coach Erik Spoelstra said "everything's fine'' and that there is no reason for concern over.

Butler was a big offseason acquisition for the Heat this past summer, agreeing to a four-year deal in a sign-and-trade with Philadelphia.

Miami is also without guard Dion Waiters for the opener while he serves a one-game suspension for conduct detrimental to the team.
