Chicago Blackhawks defenceman Duncan Keith has been offered an in-person hearing with the NHL’s department of player safety to discuss his high-sticking of Minnesota Wild forward Charlie Coyle.

Because Keith’s hearing was offered in-person, his potential suspension could exceed the five regular-season games remaining in Chicago’s schedule.

Keith’s availability for Game 1 of the defending champions opening-round playoff series is now in jeopardy.

“We’ve missed guys all season long, so I’m not worrying about hypotheticals,” Chicago coach Joel Quenneville told reporters.

The two-time Norris Trophy champ and reigning Conn Smythe Trophy winner was handed a match penalty for the stick-swinging incident, which occurred midway through the first period of Chicago’s 4-1 loss to Minnesota Tuesday night. Watch the play:

Keith is not officially considered a repeat offender by the league because he has a clean slate over the last 18 months, but the No. 1 defenceman does have a history of egregious offences.

In 2012, Keith was assessed a five-game suspension for a brazen elbow to the head of Vancouver Canucks star Daniel Sedin.

More relevant to the Coyle play is what Keith did in 2013. During Game 3 of the Western Conference final against the Los Angeles Kings, Keith was suspended one game for this retaliatory high stick to the face of Jeff Carter.

Chicago has clinched a post-season berth but is still battling for home-ice advantage in Round 1. The Blackhawks are currently without their No. 1 goaltender, Corey Crawford, who is dealing with an upper-body injury.
