Has a woman ever played a game in the NHL?
In the regular season, no. In the preseason, yes. Goaltender Manon Rheaume played one game in each of the 1992 and 1993 preseasons for the Tampa Bay Lightning. She was the goaltender for the women's Canadian national team that won world championships in 1992 and 1994 and the silver medal at the 1998 Olympics.
