Kaiden Guhle will be out for four to five weeks after undergoing minor surgery on his adductor muscle over the summer, the team announced on Wednesday.
The 24-year-old has faced a significant number of injuries throughout his four-year career, causing him to miss over 115 games due to multiple upper-body and lower-body injuries.
Last season, Guhle also missed 39 games due to a partially torn adductor muscle.
In his 208 career games, the former 2020 first-round pick has racked up 18 goals and 51 assists.
Montreal will begin their season on September 29 in Toronto against the Maple Leafs.
