EDGE Analysis

With blueliners Cody Ceci (lower body) and Marc Methot (hand) both ailing, it was imperative that the Sens' captain return to the lineup as soon as possible. He missed a total of two games with the undisclosed injury, and will look to further help solidify Ottawa's playoff berth while building on his 68 points.
