The Heat expects to be without four rotation players when it opens the regular season Wednesday at Orlando.
The Heat indicated Wayne Ellington and Justise Winslow are doubtful to play, and James Johnson and Dion Waiters are out as they recover from surgeries earlier this year.
Johnson, who had sports hernia surgery in May, has participated in two practices, but the Heat wants him to do more in practice before returning.
Miami is being cautious with Ellington, who said his ankle is healed and could play if absolutely needed.
