CHICAGO — In some Chicago circles, certainly every one that includes a hockey rink, it’s just “Q.” Only one letter is necessary for a man so revered there is a Twitter account for his mustache with more than 40,000 followers.

Q returned Tuesday night.

Joel Quenneville led the Panthers into Chicago to take on the Blackhawks for the first time since his wildly successful run in the Windy City ended some 14 months ago.

The 61-year-old Quenneville coached the Blackhawks to three Stanley Cup championships and nine playoff appearances in 10-plus years before he was fired when the team got off to a lackluster start last season. He was hired by the Panthers in April, setting up a big night for the coach and his former players.

“He’s like an icon in Chicago, whether it’s him winning three Stanley Cups, coming in and helping us become better players,” Blackhawks star Patrick Kane said. “What he’s done here in his career is amazing, he’ll get a warm reception and it’ll be good to see him. We’ll try to get a win against him and enjoy the time.”

The Blackhawks had made just one playoff appearance in 10 years when Quenneville took over four games into the 2008-09 season, replacing Hall of Famer Denis Savard. Dale Tallon was the GM for the Blackhawks at the time, and he hired Quenneville again with the Panthers.

The Blackhawks won the Stanley Cup in 2010, 2013 and 2015.
