Jeník, who hails from Nymburk, a town of 15,000, suffered a season-ending injury at the 2020 World Junior Championships in the Czech Republic.
"It was definitely a hard moment for me to basically try to get back on my feet," Jeník said. "But I like challenges, and that was a big challenge for me. I had a great group of people around me and they just helped me to get through it. I would say now, I'm only stronger."
Prior to his injury, Jeník totaled 56 points (22G, 34A) in 27 games in his final OHL season in 2019-20 with the Hamilton Bulldogs. He was on pace to contend for the Ontario Hockey League scoring title.
He strung together a 26-game point streak that season, one game shy of tying John Tavares (TOR), Connor McDavid (EDM) and Alex DeBrincat (CHI) for the third-longest OHL point streak of the century.
Back to tonight: There will be emotions, and without a doubt, some jitters. Armstrong put himself in Jenik's skates for a moment when asked what he expected to see from the debut.
"That's a hard one, you never know," Armstrong said. "It's a pretty nerve-wracking experience. You hope that he just really settles in and concentrates on playing the same way that he did (at Tucson).
"We're excited to get to see him play in the National Hockey League."
