According to the Boston Herald the NHL has chosen Fenway Park, as the host of the 2010 NHL Winter Classic.
The report states Boston was chosen over New York and Philadelphia to host next season's ode to alfresco hockey and the opposing team is likely to be either the Rangers or the Montreal Canadiens, though nothing has been officially decided.
NHL officials had looked at playing the game in Fenway Park, home of Major League Baseball’s Boston Red Sox, or Gillette Stadium, home of the National Football League’s New England Patriots. However, fears over the NFL playoff schedule conflicting with the NHL's preferred January 1 date led the league to choose the historic baseball park over the larger capacity offered by Gillette.
The 2009 Winter Classic was played in front of 41,000 fans at Wrigley Field in Chicago as the Blackhawks were defeated by the Detroit Red Wings 6-4. The 2008 game featured the Buffalo Sabres and Pittsburgh Penguins in front of 71,217 at Ralph Wilson Stadium in upper New York. The Pens took that tilt in a shootout 2-1 on Sidney Crosby’s winner.
