MONTREAL -- Scott Upshall scored with 3:04 remaining in the third period and the Philadelphia Flyers advanced to the Eastern Conference finals with a 6-4 victory over the Montreal Canadiens on Saturday night.
The Flyers are the second team to reach the conference finals after the Presidents' Trophy-winning Detroit Red Wings won the West by sweeping the Colorado Avalanche.
Philadelphia will face the winner of the Pittsburgh Penguins-New York Rangers series.
The Penguins lead 3-1 and Game 5 is today in Pittsburgh.
The Flyers' win also assured the first all-U.S. Stanley Cup final since 2003 and extended Canada's title drought to 15 years.
Montreal was the last Canadian team to win the Stanley Cup -- in 1993.
Umberger scored his second goal of the game at 15:44 to tie it at 3-3 and Scott Hartnell's third goal of the playoffs at 17:00 gave the Flyers their first lead of the game at 4-3.
