Calgary Flames goaltender Karri Ramo is expected to be out until after the Olympic break with a sprained medial collateral ligament in his right knee sustained during the Flames' game Saturday against the Minnesota Wild.
Ramo left the game with 2:28 remaining in the first period.
"[Ramo] came at a TV timeout and he told me, 'Bob, I can't keep going,'" Flames coach Bob Hartley said Saturday. "Right away, we went to Reto. I went to see [Ramo] after the first period and he was sore. I don't think that it's major but obviously you never know. I'm not a doctor."
Ramo is 11-10-4 with a 2.68 goals-against average and .908 save percentage in 29 games. It's Ramo's first NHL season after playing the past four seasons with Avangard Omsk in the Kontinental Hockey League.
Berra, a 27-year-old rookie in his first North American season, is 7-14-2 with a 3.20 GAA and .891 save percentage in 24 games.
Ortio, 22, was a 2009 sixth-round draft pick (No. 171) skating in his first full North American season. In 25 AHL games he is 19-5-0 with a 2.08 GAA, .930 save percentage and two shutouts. He's second in the AHL in wins and third in GAA and save percentage.
