Mrtka was Buffalo's 2025 1st round pick (9th overall) and has signed a three-year, entry-level contract with the Sabres on Tuesday. The 18-year-old Czech defenseman spent 2024-25 as an import player with Seattle (WHL), where he excelled with three goals and 35 points in 43 games played. He is expected to return to the Thunderbirds for the 2025-26 season but will get a chance to make an impression in training camp.
