Calgary Flames defenseman Dennis Wideman will plead his case to the league next week.
The 32-year-old's appeal hearing has been scheduled for Wednesday in New York City.
Wideman is appealing the 20-game suspension he was assessed after hitting linesman Don Henderson in a game against the Nashville Predators on Jan. 27.
