Some very special pieces of Canadian Olympic hockey equipment are missing.

The gloves and stick used by Sidney Crosby to score the winning goal in Canada's gold medal victory over the U.S. at the Vancouver Winter Olympics on Sunday are unaccounted for, Hockey Canada said Tuesday night.

Crosby flung the equipment into the air after his overtime goal in Canada's dramatic 3-2 win.

"After the game, with all the celebration and everything, the equipment was all collected and it was being put in the players' bags," said Johnny Misley, Hockey Canada's executive vice-president of hockey operations.

"[It] was noticed that Sidney's stick — that he scored the winning goal with — and his gloves, were missing. We're doing a little bit of an investigation to find out what happened."

Misley said the Hockey Hall of Fame initially requested Crosby's stick for its collection.

"There was a request for Sid's stick at the time, but at that time we knew it was missing so we couldn't give it to them."

The Hall did receive some equipment from members of Team Canada, Misley added.

It's not the first time some of Crosby's gear has vanished.

In 2005, the Cole Harbour, N.S., native's jersey disappeared after Canada's gold-medal win over Russia at the world junior hockey championship in Grand Forks, N.D.

It was later found in a mailbox outside a post office in Lachute, Que.

At this point, it's not clear what happened to Crosby's game-winning gloves and stick, Misley said.

"We don't know if it's mixed in with other equipment right now or if, in fact, it was taken. We don't know. We don't want to speculate anything at this point until we get some more information."
