The Miami Heat got smashed by the Boston Celtics in Summer League play while Heat players Chris Bosh, Hassan Whiteside, and Josh McRoberts attended the game in Las Vegas. The real loss didn’t come from the score but when Heat rookie Justise Winslow injured his ankle in the second quarter and didn’t come back. Winslow played less than 11 minutes and was 1 for 5 when he turned his ankle on offense and with no contact. It is believed to be a sprain and Winslow will be evaluated. Las Vegas Summer League Tournament runs until Monday and if the Heat are smart Winslow would not be playing again.
