Walker grimaced in pain as he went down and play was stopped as medical personnel from both teams tended to the star guard who was prone on the floor for several minutes. His teammates gathered round as did Nuggets players, plainly concerned about Walker. A brace was placed around his neck to stabilize the area and he was strapped to a backboard before being placed onto a gurney and wheeled off the court in front of a hushed crowd.
"I saw him in the ambulance at halftime," Celtics coach Brad Stevens said. "He had his wherewithal about him. He was in decent spirits, which is good."
In a tweet, the Celtics said Walker has been diagnosed with concussion-like symptoms and was transported to a hospital for further evaluation.
Walker, the Celtics' leading scorer, had three assists and a pair of steals before leaving the game.
"Our prayers and our energy are with him," Jaylen Brown said. "He's probably the smallest dude on the floor every time he steps out, but he's probably got the biggest heart. We definitely lean on him and we'll welcome him back when he rests up and everything is taken care of."
Earlier this month, the Celtics lost Gordon Hayward to a fractured left hand. He suffered the injury when he collided with LaMarcus Aldridge in a Nov. 9 game against San Antonio.
After receiving medical evaluation, Walker was released from the hospital Friday night so he could return to Boston with his team.
Unfortunately for the team, the Nuggets beat the Celtics 96-92.
