Anze Kopitar didn’t know anything was wrong until he saw Jeff Carter wearing a walking boot Friday morning. Carter suffered an unspecified lower-body injury during the Kings’ 4-3 overtime victory over the San Jose Sharks on Wednesday.

The Kings were expected to place Carter on injured reserve later in the day and to announce the promotion of one or more players from their American Hockey League affiliate in Manchester, N.H. In addition, they placed defenseman Keaton Ellerby on waivers earlier Friday.

“It’s definitely tough to see whenever a player goes down, regardless of who he is,” Kopitar said after the Kings’ practice. “With Jeff, it’s definitely a loss for us, but that’s the way it is. We’re going to have to find a way to score goals, put up points and win hockey games at the end of the day.

“So, with him or without him, we’re going to have to do that. It’s certainly a loss. We’ve got the confidence in here that we’re going to pick up whatever needs to be picked up. Personally, I’ll go out there and do the same stuff over and over again. That’s really all I can do, and all anybody else can do.”

Carter is tied with Justin Williams for the team lead with five goals.

Kings coach Darryl Sutter bristled when reporters tried to ask about Carter.

“Where do you get your information from?” Sutter said. “Is there someone in the organization who told you? You go talk to them. There were several players who weren’t out there today. I’m disappointed information was given to you before it was given to us. That’s disappointing.”
