Four final candidates were in the running for the vacancy -- Murray, Benning, Mike Futa (Los Angeles' co-director of amateur scouting) and Brad Treliving (Phoenix's VP of Hockey Operations & Assistant GM) -- but it appears Sabres President of Hockey Operations Pat LaFontaine has made his decision.
TSN Hockey Insider Bob McKenzie indicated on Twitter that "pending successful negotiation of (a) contract," Murray will become the Sabres' new GM.
The two sides still need to work out the parameters of a contract, as of Tuesday evening.
Murray was named Ottawa's Assistant GM on July 5, 2007. He has also served as the GM of the team's American Hockey League affiliate, the Binghamton Senators.
He first entered the NHL in 1993-94 as an amateur scout with the Detroit Red Wings. In 1994, he joined the Florida Panthers in the scouting department and left as the club's Director of Amateur Scouting.
Murray served as Director of Player Personnel with the Anaheim Ducks from 2002-03 to 2004-05 before moving to the New York Rangers as Assistant Dir. of Player Personnel in July 2005.
Several teams have expressed an interest in some of Buffalo's players, though the team has primarily wanted to wait until a new GM was hired to handle those calls.
The Sabres and Montreal Canadiens had discussed a deal involving former Sabre Daniel Briere over the weekend and those talks will likely resume with Murray at the helm in Buffalo.
