Alan Thicke, an actor best known for his role as Jason Seaver on "Growing Pains," died Tuesday at the age of 69.
Thicke was a huge hockey fan and close friends with Wayne Gretzky, who shared his thoughts on Thicke on Thursday via social media.
NHL Commissioner Gary Bettman said Thicke will be greatly missed.
"In addition to being a passionate fan, Alan was an energetic participant in many of our events, including All-Star, charity games and Awards shows," Commissioner Bettman said Thursday. "He frequently attended games and was with us as recently as September's World Cup.
"Alan always displayed humor and grace and he will be greatly missed. We send condolences to Alan's wife, Tanya, and the rest of his family as well as to his countless friends and the multitudes he entertained."

Upon news of Thicke's death, many people from the hockey community and entertainment industry offered their condolences on social media,
Thicke was born in Kirkland Lake, Ontario, and grew up playing hockey and football, though his love of hockey was well-known, from his Los Angeles Kings fandom to his relationship with Gretzky, among other NHL greats, to his frequent involvement with NHL events.
In a 2014 profile by Grantland, Thicke described how hockey helped make him feel at home when he moved to Los Angeles in 1970.
"When I first came to Los Angeles -- literally the first week when I was still staying in a motel -- I was looking to establish some element of familiarity," he said. "And as a lonely Canadian, I looked in the newspaper to see if the Kings were playing Saturday night."
As Thicke gained fame in Hollywood, he used his celebrity and his friendships with NHL players to help raise the sport's profile in the United States.
Among his efforts was the "The Hockey Sock Rock," a song he wrote for the New York Rangers and the NHL in 1979. Rangers Phil Esposito, Ron Duguay, Dave Maloney, John Davidson and Pat Hickey performed the song on the record, with proceeds going to the Juvenile Diabetes Research Foundation.
The record had a B side track called "Forgive My Misconduct," performed by Kings players Marcel Dionne, Charlie Simmer and Dave Taylor.
Thicke became friends with Gretzky, then captain of the Edmonton Oilers. Gretzky was at Thicke's home, babysitting Alan's son Robin, when he received the call he'd been traded to the Kings in 1988.
"Outside of the Oilers and the Kings and my wife and I, he was the first person that knew the trade was going to happen," Gretzky told Grantland in 2014. "I knew he wasn't going to say anything. Most importantly, he was probably the biggest L.A. Kings fan in town, so he probably wanted it to happen more than anybody."
Thicke grew into a great ambassador for the game through the past 40 years, lending his humor and show business savvy to some of the League's biggest events. He hosted the NHL Awards in 1988, kicking off the night with a memorable musical number.
In 1992, he served as master of ceremonies at Expo Hall for the Tampa Bay Lightning's first game.
Thicke remained a huge Kings fan, while pulling for his hometown Toronto Maple Leafs, and continued to be around the game he loved.
