The Heat sat in zone for most of the night, and the Sixers ran out of solutions on offense in the middle of the third quarter en route to a 109-104 defeat.
With Joel Embiid ruled out shortly before game time, the Sixers lacked focus on offense and effort on defense until it was too little too late in a 124-114 defeat.
And so, on the day that he was expected back at practice in anticipation of a potential season debut on Thursday, James Harden is instead packing his bags for Los Angeles.
