Allowing women to enter the NFL?

I just saw an article saying that starting in 2012, the NFL will be forcing teams to have women on every team, an equal amount of men and women on a team. Also, women must start as well. This seems ridiculous to me, which is why I'm beginning to question the legitimacy of the website I got this from, Weekly World News. Is this like a joke news station or tabloid, like The Onion? Please explain.
