It didn't take long to find out after Blues Pavel Buchnevich and David Perron would attack Kadri after the Avalanche made the game 3-1, Buchnevich would cross check him then Perron basically attacked him. Kadri would keep his composer and didn't retaliate.
That wasn't all that happened though as after Kadri scored to make it 4-1, Perron would then try to end Kadri's Playoffs by trying to elbow Kadri in the head, thankfully for Kadri, Perron missed and once again Kadri didn't lose his composer or retaliate.
