Johnny Quinn told fans via Twitter that he was taking a shower at the athletes' village when the door somehow locked and jammed, leaving him stuck inside.
"With no phone to call for help, I used my bobsled push training to break out. #Sochijailbreak," the tweet said. The Chicago Tribune said the message came with a photo of the door with a sizable hole in it.
Quinn, a push man on the U.S. 4-man team, weighs 218 pounds and used to play pro football in Canada, the newspaper said.
