In a game filled with tension and emotions, Toronto Maple Leafs defenseman Morgan Rielly finds himself at the center of controversy. The 11-year NHL veteran is likely to be handed supplemental discipline for the first time in his career after delivering a cross-check to the head of Ottawa Senators' Ridly Greig late in the game.

The incident occurred in the closing seconds of the Senators' 5-3 victory over the Maple Leafs. After Greig scored an empty-net goal from close range, Rielly responded with a forceful cross-check to Greig's head along the side boards. The referees immediately penalized Rielly with a five-minute major and a game misconduct.

Despite the on-ice repercussions, Maple Leafs coach Sheldon Keefe defended Rielly's actions, deeming them as a natural reaction in the heat of the moment. Keefe stated, "He's reacting to a play. Their player has the right to react in that moment, and our players have the right to react. That's the emotion of the game."

However, the Senators held a different perspective on the incident. Interim coach Jacques Martin expressed his disapproval, referring to it as "not a hockey play." According to Martin, Rielly's cross-check was driven by frustration rather than being a part of the game.

The league is expected to review the incident, raising the possibility of supplemental discipline for Rielly. This would mark the first time Rielly has faced such disciplinary action throughout his lengthy NHL career.

The game also witnessed tensions rise during the final faceoff when the Maple Leafs brought out enforcer Ryan Reaves. However, the officials promptly intervened to prevent any further escalation.

Despite the differing opinions, the Senators appeared to take the incident in stride. Senators' center Josh Norris, who scored a goal in the game, commented, "I didn't really like the retaliation, but I understand their frustration, but it's over with, and I guess it was entertaining."

In addition to the controversial incident, the game itself showcased notable performances from Ottawa players. Shane Pinto gave the Senators a 3-2 lead in the second period with a deft tip, while also contributing two assists. Norris scored a crucial goal with 4:47 remaining in the period to extend Ottawa's lead, and Max Domi scored to bring the Maple Leafs within striking distance at 4-3.

As the league investigates the incident and deliberates on the appropriate course of action, the incident between Rielly and Greig serves as a reminder of the intense emotions that can arise during exhilarating NHL matchups.
