New York Islanders winger Anthony Duclair suffered a significant leg injury during a game against the Montreal Canadiens, potentially sidelining him for the long-term. The injury occurred with minimal contact, raising concerns due to Duclair's previous Achilles injury on the same leg. Despite the severity of the situation, Islanders' GM Lou Lamoriello stated that it is not season-ending, though further testing is required to determine the exact recovery timeline. Duclair, who signed a four-year, $14 million deal with the Islanders, has been a key player on their top line, contributing three points in his first few games. His absence is a substantial blow to the team's offensive strategy, prompting potential lineup adjustments including Anders Lee stepping up and Simon Holmstrom seeing more power-play time. The Islanders are expected to recall a forward from their AHL affiliate in Bridgeport to fill the gap left by Duclair.
