On Monday night, the Flyers announced their opening night roster, which features all the popular names you'd expect. However, defenseman Cam York was placed on injured reserve [https://www.nhl.com/flyers/news/flyers-announce-2025-26-opening-night-active-roster], allowing veteran defenseman Dennis Gilbert, who was waived [https://thehockeynews.com/nhl/philadelphia-flyers/latest-news/flyers-make-final-roster-cut-top-prospect-poised-to-stay-in-nhl] during Saturday's 4-3 preseason shootout win over the New Jersey Devils, to remain on the NHL roster. Aside from York, Rasmus Ristolainen, Oliver Bonk, and Ethan Samson were each listed as injured non-roster players. York, 24, played a team-leading (tied with Travis Sanheim) 25:28 against the Devils on Saturday, but received treatment after the game. Flyers Preseason Stock Up, Stock Down: Chemistry and Causes for Concern [https://deweb-519a7.b-cdn.net/post-images/e107fec7-71ad-4c6d-a5db-703d8513e686.jpeg] Flyers Preseason Stock Up, Stock Down: Chemistry and Causes for Concern The <a href="https://thehockeynews.com/nhl/philadelphia-flyers">Philadelphia Flyers</a> finished the 2025 preseason with a 3-4-0 record, needing a shootout to achieve each of those three wins. Despite some new players impressing, there are causes for concern, too. [https://thehockeynews.com/nhl/philadelphia-flyers/latest-news/flyers-preseason-stock-up-stock-down-chemistry-and-causes-for-concern] Because York is on injured reserve, he must miss a minimum of seven days, which rules him out for the first three games of the season: Florida away, Carolina away, and Florida home. Dubiously, Emil Andrae [https://thehockeynews.com/nhl/philadelphia-flyers/latest-news/flyers-reportedly-open-to-trading-emil-andrae] was not re-called from the AHL Lehigh Valley Phantoms to fill the void left by York, leaving power play opportunities to Sanheim and Jamie Drysdale, as well as, potentially, Egor Zamula [https://thehockeynews.com/nhl/philadelphia-flyers/latest-news/rick-tocchet-issues-blunt-warning-to-struggling-flyers-defenseman]. After playing in all 82 games in the 2023-24 season, albeit while not at 100% health, York will miss time for the second consecutive season, starting 2025-26 on the shelf and missing the home opener on Monday, Oct. 13.
