Ottawa defenseman Erik Karlsson doesn't think Penguins left winger Matt Cooke intentionally sliced mostly through his Achilles tendon with his skate blade -- "I refuse to believe that anyone would do that," Karlsson said -- but he made it clear Friday that he blames Cooke. Karlsson, injured in a Feb. 13 game at Consol Energy Center, spoke publicly for the first time. "I think the situation could have been prevented," said Karlsson, who had surgery and is expected to miss the rest of the season. "I don't think it would have happened it if was another type of player." The play happened when Cooke pinned Karlsson against the boards as the two were tracking the puck. "As soon as I see it's him, I know what's going on," Karlsson said. "I've been around long enough to know who's going to hit you and who's not. As I always do, I moved in the last second, and he misses me. He still reached for me. "I lost the strap on my helmet. His hands are high. He reached out his leg, which I don't think he has any reason to do. That's why it happened. He has full control of his body. He knows exactly what he's doing out there, and that's why I'm sitting here with my leg in a cast.
