He was at the NHL event to award the Hart Memorial Trophy, which recognizes the league’s most valuable player.
Trebek spoke about being a huge fan of the sport and remarked on the teams and players he watched in his youth.
“It’s a great thrill for me to be here tonight to hand this trophy to the best of the best of this new generation,” Trebek said.
The award was presented to Nikita Kucherov, a right winger for the Tampa Bay Lightning.
Trebek's cancer treatment is ongoing. Last month, he shared that his doctors said his disease is in "near remission" after his first round of chemotherapy.
