Kristaps Porzingis

Horford continues to start for Boston with Kristaps Porzingis out. He had another vintage Horford performance against the Cavs with 20 points on 11 shots, four made 3-pointers and three blocks. The Celtics as well as fantasy owners can't ask for much more from the 38-year-old big man. Boston is back in action on Friday against the Wizards.

Porzingis does not have a timeline for return after undergoing offseason surgery, but he is making strides. He practiced with the Celtics' G League affiliate on Monday and did not experience any issues. "All I know is he's getting better every day, and he's working really hard at coming back as fast as he can," Mazzulla said of Porzingis. "He's in the next phase." Al Horford has handled the starting center duties in KP's absence, with Neemias Queta and Luke Kornet taking on increased workloads.

When could Kristaps Porzingis return to action? And are the Cavs the real deal? Chris Forsberg tackles your Celtics questions in a brand-new mailbag.

Chris Forsberg reacts to the Celtics announcement that Kristaps Porzingis has moved to the next step in his recovery process from offseason surgery and explains why he thinks the big man could return by early December.

Porzingis and Xavier Tillman were assigned to practice with Maine, and they will be recalled immediately to the parent club following the practice. Porzingis is inching closer to a return, but until he's back on the court, Al Horford should hold down the starting center job for Boston.
