This weekend marks 40 years since the Miracle on Ice.
That is when the U.S. Olympic hockey team pulled off one of the biggest upsets in sports history by beating the team from the Soviet Union.
In honor of the anniversary, the Vegas Golden Knights are hosting a Miracle Weekend.
It starts today at The Arsenal at City National Arena.
Jim Craig, the starting goalie for the 1980 team, will be signing copies of his book from 3 to 5 p.m.
On Saturday, the Olympians will be given keys to the Las Vegas. It will happen on Toshiba Plaza right before the Golden Knights' game.
