EL SEGUNDO, Calif. -- Los Angeles Kings winger Brad Richardson had an emergency appendectomy and is unavailable for the immediate future, coach Darryl Sutter said Tuesday.
Richardson had symptoms "the last couple of days" and had the procedure done Monday night, according to Sutter.
Sutter had no idea how long Richardson will be out, but Richardson is expected to at least miss Game 1 of the Western Conference Quarterfinals on Wednesday in Vancouver.
Sutter said he underwent the same procedure four or five years ago when he was with the Calgary Flames.
"Better to have it out than have it ruptured, because it's not about hockey," Sutter said. "The procedures they have now -- you're resuming activity within a couple of days. You know what? We won't have him for a while."
Richardson was inserted on the top line when Jeff Carter had a bone bruise. Richardson had two goals against Minnesota on March 31 and an assist against Edmonton on April 2 in Carter's absence.
"We played without Carter," Sutter said. "We've been short, so we know [what it's like]."
The Kings have recalled center Andrei Loktionov from Manchester of the American Hockey League.
