Lindy Ruff, the longest-tenured coach in the National HockeyLeague, was fired as coach of the Buffalo Sabres on Wednesday despite being the most successful coach in the club’s history.

Ruff had compiled a record of 571-432-162 in 15 seasons since taking charge of the Sabres in 1997, but was axed after the team stumbled to a start of 4-10 with one over-time loss and fell to 11th among 15 Eastern Conference teams.
