This is from Rotoworld:
“Kemba Walker (neck) was taken off on a stretcher against the Nuggets on Friday.
He was going for a loose ball and went head first right into Semi Ojeleye's chest. Walker likely hurt his neck and the medical staff strapped him in as they took him off the court. Walker did appear to be talking and he was moving his arms, so hopefully the staff was just being careful. The Celtics will have to turn to Carsen Edwards and Brad Wanamaker to help out Marcus Smart with Edwards offering more upside.”
Hopefully he’ll be able to come back sometime during the season.
