"It's a dirty vicious hit, up high, he put Ballard into the Glass," Minnesota Wild color commentator Mike Greenlay said.
You can decide for yourself what you think of the hit. I agree with Wes Walz, it's a questionable hit. It's in the grey area. The thing that might do Martin in, he came from a long way to hit Ballard and he was injured on the play.
If you watch the video, it looks like an elbow "might" have made contact with the head.
