IN OTHER NEWS…

LOS ANGELES TIMES: Anaheim Ducks goaltender Ryan Miller has announced his retirement at the end of this season. He’s spent 18 seasons in the NHL with the Buffalo Sabres, St. Louis Blues, Vancouver Canucks and the Ducks. Miller spent nearly 11 seasons with the Sabres, winning the Vezina Trophy in 2009-10. He leads all American-born NHL goalies with 390 wins and sits second with 44 shutouts and 794 games played. He’s 14th on the all-time wins list.

SPECTOR’S NOTE: Miller was in his prime during his years with the Sabres, backstopping them to back-to-back Eastern Conference Finals in 2006 and 2007. He was also named MVP of the 2010 Winter Olympics as Team USA won the silver medal in Men’s Hockey. Best wishes to Miller and his family in their future endeavors.

TSN: The NHL is expected to reach a decision between June 1-5 as to where the winner of the Scotia North Division will play its home games. Discussions between the league and the Canadian federal government are ongoing.

SPECTOR’S NOTE: The ongoing closure of the Canada-US border to non-essential travel and traffic could mean whoever comes out of the North Division will have to play all their remaining playoff games in the United States. That means the league will have to find a suitable venue to host the Canadian team.

THE AHL: announced the Calder Cup won’t be awarded this season. Instead, the Pacific Division will hold a tournament to decide its division champion. The first-place teams in the other four divisions will be named division champions.

CALGARY SUN: Original Flames co-owner Byron J. Seaman passed away last weekend at age 97. He was among the ownership group that moved the Flames to Calgary from Atlanta in 1980 and held a stake in the franchise for the next three decades.

SPECTOR’S NOTE: My condolences to Seaman’s family, friends and the Flames organization.
