Ottawa's bigger loss was defenseman Erik Karlsson. Last season's Norris Trophy winner sustained a cut left Achilles tendon. Penguins wing Matt Cooke checked him into the boards late in the second, and his skate blade sliced the tendon of Karlsson, 22, who is out indefinitely.
Ottawa captain Daniel Alfredsson questioned the hit by Cooke, who has been suspended by the league for hits four times.
"I don't know if it was intentional," he said. "But why would you hit someone that way?"
Cooke denied going after Karlsson.
"He and I were engaged. He went down screaming," Cooke said. "I didn't even know what happened."
Ottawa already is without its top center, Jason Spezza (herniated disc). Wing Milan Michalek, third on the team with eight points, was scratched Wednesday (lower-body). And wing Guillaume Latendresse (whiplash), center Peter Regin (chest) and defenseman Jared Cowen (hip surgery) remain out.
Game highlights: Alexander Steen stuffed in a rebound 52 seconds into overtime as the visiting Blues beat the Wings 4-3. The Blues had lost five in a row (0-4-1) since starting 6-1.
First European GM: Jarmo Kekalainen of Finland became the first European NHL general manager, taking over in Columbus. After a short career in the NHL, Kekalainen, 46, was director of amateur scouting for the Blues (and current Blue Jackets executive John Davidson) from 2002-10. Most recently, he was a GM in Finland. He takes over for the fired Scott Howson.
Around the league: The Avs' Erik Johnson, whose average ice time of 21:07 is second among the team's defensemen, is out indefinitely with a head injury sustained Monday when he was checked into the boards. It hasn't been determined if he sustained a concussion. … Leafs wing Matt Frattin, whose seven goals are second on the team, will have knee surgery today and miss at least a week. … Penguins defensemen Kris Letang and Matt Niskanen returned. Letang missed three games with a lower-body injury, Niskanen eight with a right ankle injury. … The Devils reacquired wing Alexei Ponikarovsky from the Jets for a fourth- and seventh-round pick. He had nine points during last season's playoffs as New Jersey reached the final then signed with Winnipeg in the offseason.
