from Per Bjurman of Sport Bladet (Google translate),

It is one of the largest Swedish hockey cycles that end when Henrik Zetterberg leaves the ice.

He will be missing - in so many ways.

Yes, no - as we could already imagine when he announced in mid-August that he was unable to train throughout the summer:
Henrik Zetterberg's demolished back does not hold for more hockey matches.

So after 15 NHL seasons, 1082 prize games (plus 137 in the playoffs), World Cup Gold, Olympic Gold and Stanley Cup titles, he leaves the rink and retires.

But even if the message does not come as a shock, it feels foolishly sad.

"Zäta" is undoubtedly one of the biggest Swedish hockey players throughout the ages, and has made virtually as much impression in NHL as Peter Forsberg, Mats Sundin, Nicklas Lidström, Brothers Sedin, Börje Salming and Daniel Alfredsson.
