ORLANDO, Fla. -- Boston center Glen Davis was diagnosed with a concussion after being shaken up late in the third quarter of Game 5 of the Eastern Conference finals, needing to be held up by referee Joey Crawford to keep from falling.
Davis was struck in face by Orlando center Dwight Howard's elbow, tumbling to the court as play went the other way. Davis tried to get up, only to fall again, and then was clearly dazed when he got to his feet.
He took a few more steps, then staggered toward Crawford, who wrapped his arms around Davis to keep him upright as play stopped with 9.7 seconds left in the period. Davis was tended to on the court for a few minutes, then walked to the Celtics' bench and eventually toward the locker room for evaluation. The hit also dislodged at least one of Davis' teeth.
"Never want to see anybody, especially a friend, go down like that," Howard said.
Davis finished with four points and one rebound over 19 minutes.
Celtics coach Doc Rivers said Davis "blacked out" on the court, and the training staff will examine the forward Thursday.
"I don't know what kind of tests they're going to do with Baby. He's a little delirious anyway," Rivers said, chuckling.
When the Celtics' locker room opened following the loss the mood was glum. A series that once looked like a Boston runaway might be running away from the Celtics.
"Point blank. I ain't speaking. I'm all right. I'll be back next game," Davis said, marching through a parting wall of reporters huddled around his stall in the locker room, then shouting an expletive. "That's all you need to print."
Daniels -- like Davis -- was briefly unconscious in the second half.
Daniels got hit in the face while attempting to pass the ball (he was instead called for traveling) and was also diagnosed with a concussion. The little-used Daniels logged three minutes because of the rash of injuries and foul trouble.
"He ain't talking," Boston backup Nate Robinson said after the game, shooing reporters away from Daniels' locker.
