Mat Barzal has been fined $5,000—the maximum allowable under the Collective Bargaining Agreement—for slashing Columbus Blue Jackets forward Mason Marchment. The incident that took place during the second period of the Islanders’ matchup against the Blue Jackets on December 28, 2025.

Mat Barzal Fined for Standing His Ground

Let’s look at the tape. The chaos started at 1:34 of the second period. This wasn’t a random act of violence in a vacuum. It stemmed from Mat Barzal reacting to a play involving Mason Marchment and Islanders rookie defenseman Matthew Schaefer.

Marchment, a player who plays with a distinct edge and knows exactly how to get under an opponent’s skin, took a run at Schaefer. In the modern NHL, you cannot let your young talent get bullied, and Barzal took exception immediately. The slash was reactionary, it was emotional, and it was violent enough to earn him a major penalty and a game misconduct.

The History of Disciplinary Action

While Mat Barzal has managed to avoid the dreaded suspension designation throughout his career, this isn’t his first time writing a check to the Players’ Emergency Assistance Fund.

This marks the third time Barzal has been fined in his career. It paints a picture not of a dirty player, but of a fiercely competitive one who sometimes lets the red mist descend a little too quickly. The fact that he was ejected so early in the game likely played a significant role in his avoiding a suspension this time around.

Impact on the Islanders Moving Forward

The Islanders are a team that thrives on emotion, but they also need discipline to make a serious push this season. Losing Mat Barzal for the bulk of the Columbus game puts immense strain on the rest of the forward group. You can’t replace that kind of transition speed and vision on the fly.

However, the silver lining is that Barzal will be in the lineup on Tuesday night when the Islanders take on the Chicago Blackhawks. There was a genuine fear among the fanbase that a one-game suspension might be looming, which would have been a significant blow. Instead, Barzal gets to lace them up, lighter by five grand, but likely with his head held high in the locker room.

The Verdict on the Mason Marchment Incident

Ultimately, this is a scenario where everyone seemingly got what they wanted, even if they won’t admit it.

The NHL had the authority to enforce the rules and impose the maximum financial penalty available. Mason Marchment got to stir the pot and draw a major penalty, effectively taking the opposing team’s best player off the ice. Mat Barzal got to show his teammates, specifically the younger guys like Schaefer, that he has their back—no matter the cost.
