Heat forward PJ Tucker, sidelined since sustaining a strained calf last week against Atlanta, told Erik Spoelstra he intends to be ready for Sunday’s Game 1. “It’s encouraging,” Spoelstra said. “He’s been doing round the clock treatment. From the night he got hurt to what he just told me today walking off the court, his message has been the same. He’ll be ready and don’t think otherwise with a few other expletives.” Tucker wasn’t a full practice participant on Tuesday but shot on the side.
