Mrtka registered three assists in WHL Seattle's 5-3 win over Portland on Saturday.

EDGE Analysis

Mrtka picked up his first points in two games since returning from the World Junior Championship. He was held without a point in five tournament games for Slovakia. In the WHL, he's up to a goal and 18 helpers over 16 appearances. The Sabres prospect got a taste of AHL action this year, but the 18-year-old could return to the junior ranks in 2026-27 as well.

Mrtka notched three assists in WHL Seattle's 7-3 win over Vancouver on Saturday.

EDGE Analysis

Mrtka has settled right back in for the Thunderbirds with six assists over five games since he was transferred back to the junior team from AHL Rochester. The Sabres prospect will continue to lead the blue line in Seattle for the remainder of 2025-26. As an import player, he will be eligible to suit up in the AHL before he's 20 years old, and that could lead to him playing for Rochester in 2026-27, as he probably doesn't have much left to learn in junior hockey.

Mrtka was loaned from AHL Rochester to WHL Seattle on Friday.

EDGE Analysis

Mrtka got a taste of AHL action, earning one assist and seven PIM in four appearances. The Sabres decided it would be better for him to develop at a lower level for 2025-26, but it wouldn't be surprising to see the Czech defenseman get another look in Rochester for 2026-27.

Mrtka (illness) was sent to AHL Rochester on Saturday.

EDGE Analysis

Mrtka didn't play in Friday's preseason game versus Pittsburgh because of an illness, but his demotion suggests he should return to action soon. The Sabres selected him with the No. 9 overall pick in the 2025 NHL Entry Draft. The Czech native will start the season with AHL Rochester, but he is also eligible to play for WHL Seattle in 2025-26.

Mrtka has been ruled out for Friday's preseason finale against Pittsburgh due to an illness, Heather Engel of NHL.com reports.

EDGE Analysis

Mrtka hasn't yet made his regular-season NHL debut, and he'll be held off the ice in his final chance to work with the Sabres before the start of the 2025-26 campaign. He was selected by Buffalo with the No. 9 pick in the 2025 NHL Draft but will likely spend most of this year with WHL Seattle.

Mrtka agreed to terms on a three-year, entry-level contract with Buffalo on Tuesday.

EDGE Analysis

Mrtka was selected by the organization with the ninth-overall pick in the 2025 NHL Draft. The 18-year-old blueliner should get a look during training camp this fall, but he figures to play the bulk of his minutes in juniors with WHL Seattle. With the Thunderbirds last year, the Czech native notched three goals and 32 helpers in 43 regular-season contests before adding another trio of helpers in six playoff appearances.
