Mark Giordano could soon be spending some time on the sidelines.
With Aho driving toward the Flames' net, Giordano bumped the Hurricanes winger, then caught him when he stuck out his back leg.
Aho was injured on the play, favoring his leg as he left. Hurricanes coach Bill Peters had no update on Aho's status following the game but noted he absorbed the hit to both his head and knee.
Giordano was assessed a match penalty on the play, meaning an automatic ejection from the game, plus a further review by the league:
"In addition to the match penalty, the player shall be automatically suspended from further competition until the Commissioner has ruled on the issue" - NHL Rule Book
Which begs the question, should Giordano be assessed supplemental discipline for Sunday's incident?
Giordano isn't the only player to be given a match penalty this season. In recent weeks, Edmonton Oilers forward Patrick Maroon and Arizona Coyotes forward Zac Rinaldo received match penalties and were later suspended for two and six games, respectively.
