He was replaced by Ben Scrivens.
Quick was in obvious discomfort when play was stopped with 1:20 remaining in OT. It appeared he sustained a lower-body injury sliding across the crease about 30 seconds earlier as the Sabres rushed toward the goal.
After briefly skating out of his crease during the stoppage, he went down to his knees, bringing the Kings’ trainer onto the ice. He went to the dressing room. Scrivens played the rest of the overtime and the shootout, in which the Sabres scored twice for a 3-2 victory.
A Kings spokesman said only that Quick was being evaluated.
"I didn’t really check," coach Darryl Sutter said after the game when asked about Quick's status. The Kings have three more games on the road this week, beginning with a visit to the New York Islanders on Thursday.
"It’s too bad," defenseman Drew Doughty said. "Hopefully he recovers quick and is ready to go."
