The Buffalo Sabres announced Saturday that president of hockey operations Pat LaFontaine has resigned and will return to work at the NHL offices in New York.

LaFontaine, who spent six seasons with the Sabres as a player, returned to the team three-and-a-half months ago when longtime general manager Darcy Regier was fired. He was hired to help oversee the team’s rebuild.

In January, LaFontaine hired Tim Murray as the next general manager of the Sabres.

Murray completed his first major trade Friday evening when starting goaltender Ryan Miller was sent to the St. Louis Blues in a transaction that included five players and two draft picks.
