Ridly Greig acknowledges he was in the wrong for his actions in a heated moment on Saturday.
The Ottawa Senators forward was asked about his sucker punch of Carolina Hurricanes defenceman Sean Walker during the team's season-ending press conference on Monday.
"I got to do a better job of controlling my emotions," Greig said.
The NHL's department of player safety announced Sunday that Greig will have a hearing for roughing Walker. If there is a suspension, it will be applied next season.
During Game 4 on Saturday, Greig and teammate Warren Foegele got tied up with Walker. While Foegele had Walker in a headlock, Greig delivered a sucker punch to the Hurricanes defender.
No penalty was called on the ice.
The Senators were swept by the Hurricanes in their first-round series following their loss in Game 4.
