Struble began the 2023–24 season with Montreal's American Hockey League (AHL) affiliate, the Laval Rocket.[2] Struble was suspended for three games by the AHL for leaving the bench after a whistle during a game versus the Manitoba Moose on November 12.[3] On November 20, 2023, he was recalled by the Canadiens after injuries to defenseman Arber Xhekaj and forward Rafaël Harvey-Pinard[2] and made his NHL debut with the Canadiens on November 22 against the Anaheim Ducks.[4] Struble scored his first NHL goal on December 9 against Devon Levi in a 3–2 shootout win over the Buffalo Sabres.[5] After the Canadiens failed to qualify for the 2024 Stanley Cup playoffs, Struble was one of four players reassigned to Laval to end the season.[6]
