The incident in question occurred following the final whistle at the end of the third period on Sunday night in Game 3 between the Oilers and Canucks. In a scrum in Vancouver's zone, McDavid and Soucy each slashed each other before the Canucks defenceman caught the Oilers captain in the face with a cross-check.
Soucy was given the only penalty on the play, for his cross-check and the NHL will now be reviewing it and having a phone hearing with the Canucks blue liner on Monday. It'll be interesting to see what comes of the hearing with Carson Soucy and how many games the league will suspend him for.
