NEW YORK (Reuters) - The Buffalo Sabres rewarded Lindy Ruff, the NHL's longest-tenured coach, with a multi-year contract extension on Friday just three days after his team was eliminated from the first round of the playoffs.

Details of the contract were not disclosed.

Ruff, a former player for the Sabres, led the Sabres to a 43-29-10 record this season before losing in seven games to the Philadelphia Flyers in the Eastern Conference quarter-final.

"I said I wanted to win a Stanley Cup for the city and I'm not willing to quit yet," Ruff told reporters. "That's my goal, it's been my goal for a long time since I was here as a player and I want to bring it to fruition."

Ruff, a former Jack Adams Award winner as coach of the year, is coming off his 14th season behind Buffalo's bench, where he improved his record to 526-418-132 and became the franchise's most successful coach.

Ruff, second on the all-time lists for most games coached and most wins with one team, has led Buffalo to four Eastern Conference finals appearances, a President's Trophy winning season and a Stanley Cup Finals loss.

During Ruff's time in Buffalo there have been 162 coaching changes in the NHL.
