Anthony Mantha will miss the rest of the season due to a torn ACL suffered in a game against the Montreal Canadiens. The injury occurred after a hit from Emil Heineman, leading to Mantha's exit just 5:06 into the first period. He will undergo surgery soon. Mantha signed a one-year, $3.5 million contract with Calgary as an unrestricted free agent after a season with the Capitals and Golden Knights. He had recorded four goals and seven points in 13 games with the Flames. Over his career, he has amassed 146 goals and 303 points in 507 NHL games, and he can become a free agent again on July 1.
