Pittsburgh, PA (Sports Network) - Ottawa Senators defenseman Erik Karlsson left Wednesday's game against the Pittsburgh Penguins with a cut to his lower left leg.

Late in the second period, Karlsson and Pittsburgh's Matt Cooke met along the boards while chasing down a puck. Cooke's left skate appeared to graze Karlsson near the left ankle on the play.
