Agree. In the seconds leading up to the incident, Cernak was fairly stationary watching Dahlin. As Dahlin moved towards him, Cernak attempted a one-handed poke check with his left hand and missed. Dahlin made his backward pass, but continued advancing towards Cernak's position near the face-off dot. Cernak was waiting for him there and immediately raised his left elbow in the direction of Dahlin's head. To my eye, it looked he intentionally raised his left elbow when he could have easily used his shoulder to take the body instead.
