The Boston Celtics big man Robert Williams rejoined the team on the road as he ramps up his rehab as he recovers from Sept. 23 left knee surgery.

“I’m stepping it up,” he said, via ESPN. “They just try to hold me (back from) being a little too explosive sometimes.”

After the Celtics’ win over the Knicks on Saturday night, Jaylen Brown talked about playing without Williams: “Obviously Rob makes the game easier for a lot of us, offensively and defensively.”
