OTTAWA - Matt Cooke won’t get the book thrown at him.

The Ottawa Senators will be without defenceman Erik Karlsson for the balance of the season, but the Pittsburgh Penguins’ fiesty winger won’t get any league discipline after his skate cut the Norris Trophy winner’s Achilles tendon.

While VP of safety Brendan Shanahan took several looks at the replay of the incident Wednesday night in Ottawa’s 4-2 loss in Pittsburgh, it was decided Cooke won’t face a hearing.

Cooke took Karlsson into the boards from behind during the second period, with one skate lifted off the ice. As they hit the boards, the skate came down and landed just above the protected area of Karlsson’s skate. Cooke’s skate blade then hit Karlsson’s achilles, causing him to collapse to the ice in pain.
