Kahun did not arrive in Buffalo for practice and will instead meet the Sabres in Denver, where they open a four-game road trip against the Colorado Avalanche on Wednesday. Colin Miller also did not practice due to personal reasons.
Kahun, who was acquired yesterday in exchange for forwards Conor Sheary and Evan Rodrigues, spoke with the Buffalo media during a conference call Tuesday to express his excitement in joining the team.
"When I got traded yesterday, first of all, I was a little shocked, I didn't see it coming," he said. "But I'm really, really happy to play for Buffalo now."
He has 27 points (10+17) in 50 games this season. He's missed the last two with a lower-body injury and sat out eight games earlier this calendar year with a concussion. He suited up for 82 games as a rookie with the Blackhakws in 2018-19.
He's hopeful he can make his Sabres debut tomorrow night, but his status will be determined after he meets with the team's medical staff.
He already has some familiarity with the Sabres' coaches. He and assistant coach Don Granato were both with the Blackhakws last season and Kahun played with Krueger's son in Germany.
"Dominik, he's definitely a skilled player. He's got good hands, good feet, good speed, and he can play up and down the lineup," Krueger said. "We don't have that classic top six, bottom six kind of situation here. We really are doing this by committee right now, and everybody knows it."
While Kahun will start on the wing, there is a possibility he could move to center at some point. Kahun played down the middle until he arrived in the NHL last year.
"I think it's positive that I can be anywhere, like winger or center, but most of the time, I've played center," he said.
