At 7:19 of the second period, Fraser was hit into the boards by Maple Leafs forward Frazer McLaren. Fraser needed help off the ice after McLaren finished a check on him in front of the Maple Leafs' bench.
Fraser did not return to the game. He has one assist in 17 games this season.
"He obviously got his bell rung," Kings coach Darryl Sutter said. "We don't really know much yet."
I remember the first time at Wrigley Field all of us had the long johns, the turtlenecks and the extra equipment because we were afraid of being cold. Halfway through the first period everybody's ripping everything off and we just ended up wearing what we would normally wear for a game at the United Center.
