Here is the official announcement
The Anaheim Ducks announced today that the National Hockey League (NHL) club has acquired center Doug Weight, left wing Michal Birner and a seventh round pick in the 2008 NHL Entry Draft from the St. Louis Blues in exchange for center Andy McDonald.
“Andy McDonald has been a great contributor for us over the last few seasons, and we thank him for the tremendous work ethic and character he brought to our club,” said Executive Vice President/General Manager Brian Burke. “At the same time, we are pleased to add one of the most dynamic passers in the NHL today with Doug Weight. His production and leadership during his NHL and international career speak for themselves.”
Weight, 36 (1/21/71), scored 4-7=11 points with a +4 rating and 12 penalty minutes (PIM) in 29 games with the Blues this season. The four-time NHL All-Star (1996, 1998, 2001, 2003) has scored 4-1=5 points in his last four games.
