In case you didn't know, the Panthers have sort of adopted Spacey, 56, as the team's unofficial mascot. Whenever a player performs really well during a winning game, they're handed a blue sweatshirt with Spacey's head floating on it.
It has been dubbed the "Spacey in Space" sweatshirt and the actual meaning behind it remains a mystery.
The only one in on the team's inside joke is Spacey himself. He tweeted in December, "Only I really know what #SpaceyInSpace means. Hope it continues to bring good luck!"
Still, Spacey sported his own blue sweatshirt Saturday during the game. Masks featuring Spacey were even handed out inside the BB&T Center in Sunrise, Florida, to fans.
But Spacey's visit didn't bring much luck to the team. The Florida Panthers lost to the Detroit Red Wings, 5-3.
