Rodney McGruder already has waited four months working his way back from a broken tibia in preseason. So if he needs to wait a bit longer, he’s OK with that. McGruder has participated in two full contact practices in the past nine days - including Wednesday - and is closing in on a return. But Erik Spoelstra and McGruder were non-committal about whether he would play Friday at New Orleans. “I’ve got to work a little bit,” he said. “Being off a couple of months, you just don’t hop right back into basketball shape, so I have some more conditioning that I need to work on. I’ve been doing a little more with practicing and just conditioning, preparing myself for when the time comes on my return that I’m ready to play.”
