Cozens is the fifith Sabres player to be confirmed for the tournament, joining forwards Rasmus Asplund (Sweden) and John Hayden (United States) and defensemen Rasmus Dahlin (Sweden) and Henri Jokiharju (Finland).
Sabres coach Don Granato will also be involved in the tournament as an assistant for Team USA.
Cozens is participating in his first World Championship. He twice represented Canada at the World Junior Championship, earning gold in 2020 and silver in 2021. He was selected to the tournament All-Star Team the latter year.
Cozens, 21, tallied 38 points (13+25) in 79 games this season. He felt he made strides as a two-way player, a credit to increased ice time and responsibility in his first full year under Granato.
"I think the second half I really kind of stepped up my defensive game and reliability," he said. "That's something as a young guy I want to be reliable and trusted in the defensive zone and being able to go out there in a close game, a couple minutes left. So that's a positive I take from the second half."
