"If you look at the way the elbow comes extended, you know what you're doing," Krueger said postgame, according to The Athletic's Charlie O'Connor. "It's the fourth game where a player of ours has had a violent hit to the head and hopefully there will be action for this one."
It appeared Sabres defenseman Brandon Montour pushed Provorov into Hutton.
Provorov wasn't penalized on the play.
Hutton initially stayed in the game but didn't return following the second intermission. Krueger said after the contest that Hutton was still being assessed.
One of the other plays Krueger is referring to is likely Nic Dowd's headshot on Eric Staal last week. The Washington Capitals forward received a two-minute elbowing minor but no supplemental discipline.
