DENVER (AP) -- Jamal Murray scored 22 points, including two free throws with 1.5 seconds remaining, and the Denver Nuggets hung on to beat the Celtics 96-92 on Friday night in a game overshadowed by a head injury to Boston guard Kemba Walker.
Nikola Jokic added 18 points, 16 rebounds and 10 assists for the Nuggets, who improved to 8-0 this season when holding an opponent to fewer than 100 points.
Walker collided with teammate Semi Ojeleye late in the second quarter, striking Ojeleye's abdomen area head-first and going down on to the court in a heap.
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.
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.
The Celtics, down by 19 in the third quarter and 13 to start the fourth, went on a 10-1 run capped by Brad Wanamaker's driving layup to pull to 75-73 with 5:35 left to play.
Brown connected on a 3-pointer from the corner, pulling the Celtics to 84-83 with 2:18 remaining. Murray made a pair of free throws and hit a jumper around a Boston turnover as the Nuggets went in front 88-83. Boston added a basket but Paul Millsap connected on a 3-pointer, helping fend off the Celtics in the waning seconds.
The Nuggets took their 70-57 lead into the fourth with Michael Porter Jr. punctuating the advantage by soaring above the rim to rebound a missed shot and slam it through the net in the final moments of the third.
Denver led by 17 in the first half before the Celtics put together an 11-0 run in the second quarter, pulling to 45-34 at the half.
