If you were holding out hope for an improbably Robert Williams Game 1 return, I have bad news for you. If you expected Rob Williams to be out but were hoping to not hear of any surprise issues, then you’re in luck. Boston has a clean injury report outside of the starting center’s absence due to right meniscus surgery ahead of Game 1.
Al Horford played in the season finale, but he did note previously that he was dealing with some back issues. Those problems appear to be solved after the rest and treatment he received over the last week.
