Luck just hasn't been on the side of the Philadelphia Flyers [https://thehockeynews.com/nhl/philadelphia-flyers]' defense prospects these last few months, with another going down for several weeks with a significant injury. According to Laval Rocket and Blainville-Boisbriand Armada broadcaster Cedrik Blondin [https://x.com/cedrikblondin/status/1981850124591718408], Flyers defense prospect Spencer Gill will miss 12-15 weeks with an upper-body injury and will undergo surgery. Gill, 19, was one of the Flyers' more impressive young players throughout training camp and the preseason and seemingly made it a point to show off his playmaking and mobility in the offensive zone often. As a result, the 2024 second-round pick ranked 22nd amongst all NHL defensemen with a 67.86% Corsi percentage at 5-on-5 in his lone preseason appearance for the Flyers, according to Natural Stat Trick [https://www.naturalstattrick.com/playerteams.php?fromseason=20252026&thruseason=20252026&stype=1&sit=5v5&score=all&stdoi=oi&rate=n&team=ALL&pos=D&loc=B&toi=0&gpfilt=none&fd=&td=&tgp=410&lines=single&draftteam=ALL]. Flyers' Spencer Gill Will Be Way Better Than You Think [https://deweb-519a7.b-cdn.net/post-images/3d132137-acee-453e-a563-27b244039c8f.webp] Flyers' Spencer Gill Will Be Way Better Than You Think Spencer Gill is one <a href="https://thehockeynews.com/nhl/philadelphia-flyers">Philadelphia Flyers</a> prospect who doesn't draw nearly as much fanfare as he should, and that's not his fault. [https://thehockeynews.com/nhl/philadelphia-flyers/latest-news/flyers-spencer-gill-will-be-way-better-than-you-think] Gill's new injury marks the second major one to a Flyers defense prospect this week, as it was previously reported by The Athletic's Kevin Kurz that defenseman Oliver Bonk is still 5-6 weeks away [https://thehockeynews.com/nhl/philadelphia-flyers/latest-news/flyers-latest-injury-updates-on-ristolainen-bonk] from returning the ice. Bonk, of course, was given a two-week recovery timeline by the Flyers on Oct. 1 after being listed as day-to-day during training camp, and now he'll be missing time into December. As for Gill, the 19-year-old is missing a chunk of valuable development and playing time for the second year in a row after suffering a broken ankle last season. Gill is in his first season with the Armada after being traded [https://thehockeynews.com/qmjhl/latest-news/armada-acquire-top-philadelphia-flyers-prospect-defenseman-from-rimouski] by the QMJHL Rimouski Oceanic in the offseason. Gill hasn't played since Oct. 10; in two games this season, he has two penalty minutes, a +1 rating, and three shots on goal, but hasn't gotten on the scoresheet.
