Robert Williams was upgraded to day-to-day by the Boston Celtics on Friday.
Williams most recently underwent surgery on his left knee back in September and has missed the entire season thus far.
“The most important thing for Rob is that he’s comfortable where he’s at. From a physical conditioning standpoint and a mindset standpoint that he’s comfortable out there and that it’s going to go well for him. I think the most important thing is where he’s at and how he feels and so he’s continuing to work at it, and when he’s ready, he’s ready," said Joe Mazzulla on Williams' potential return.
