"Our trainer thinks it's either hamstring or groin-related. So it's a muscle," Kings coach Darryl Sutter said Wednesday. "He's obviously not going to play on this trip, so he might as well be home, and make sure we know what it is, and then go from there."
Sutter said Quick will be further evaluated by the team's doctors back in Los Angeles. Kings general manager Dean Lombardi told ESPN.com that Quick will have an MRI.
Quick allowed two goals and made 17 saves against the Sabres, before leaving injured with 1:20 to go in overtime. Ben Scrivens played the rest of overtime and allowed two goals in the shootout.
Scrivens will start for the Kings on Thursday against the New York Islanders, Sutter said.
