Steve Ott of the Dallas Stars, Andrew Peters of the Buffalo Sabres and James Wisniewski of the Chicago Blackhawks received suspensions Wednesday for recent separate incidents.
Ott will be out three games, while Peters and Wisniewski will miss a game apiece.
NHL discipline czar Colin Campbell suspended Ott for his hit to the head of Colorado defenceman Jordan Leopold on March 9. No penalty was assessed on the play.
The pesky Stars forward will miss Thursday's game at Detroit, Saturday's game against Vancouver, and March 19 against Anaheim. Ott, who has 20 points and a team-high 133 penalty minutes this season, will be eligible to return March 22 against Los Angeles.
Peters was hit with a one-game ban after mixing it up with New York Rangers tough guy Colton Orr on Monday night.
The Sabres enforcer got involved with Orr while still on the Buffalo bench, earning a 10-minute misconduct. Peters — who boasts two points and a team-high 100 penalty minutes — will miss Wednesday night's game in Pittsburgh.
Wisniewski received a match penalty for cross-checking Detroit's Mikael Samuelsson in the face on Tuesday night. The Blackhawks defenceman will sit out Wednesday's game against Carolina.
