Dennis Seidenberg Statement
"After fifteen years of living my dream of playing in the NHL, I have decided it is time for me to retire from the game I love. It hasn't been an easy decision, but I know it is the right one.
I want to take this opportunity to thank my coaches, teammates and the organizations I played with over the years. I have been lucky enough to represent my native Germany in three Olympic Games, an indescribable honor. There was no greater thrill than lifting the Stanley Cup with the Boston Bruins in 2011.
That group of guys will always hold a special place in my heart.
I want to thank the greatest fans of the best game in the world. I have never taken for granted what a privilege it is to play this game, and how the important the fans are. I will cherish the experiences and memories I have for the rest of my life.
Finally, I want to thank my family for all their support in letting me live out my dreams.
Thank you."
