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.
