Joe Marler could face a lengthy ban after grabbing Alun Wyn Jones by the penis in England's win at Twickenham on Saturday.
Amid a scuffle following a knock-on, the England prop was caught by TV cameras grabbing the Wales captain in the crotch area.
And according to the laws, Marler could be spending some time on the sidelines.
The low-end entry point for grabbing, twisting or squeezing the genitals under law 9.27 in World Rugby's laws is a 12-week ban.
A mid-range entry point would be 18 weeks, top-end would be 24-plus weeks and the maximum is 208 weeks.
Wales captain Jones has called for World Rugby to act afterwards.
“Yeah. It’s interesting. What would you do?” Jones said after the match.
“I’ve got 138 Tests for my country. If I react, I get a red card. It’s tough, isn’t it?
“Hopefully World Rugby have a look at it. Joe’s a good bloke, lots of things happen on a rugby field.
“It’s difficult as a captain these days because you can’t speak to a ref about anything, it feels.
“I look at the touch judge, obviously he didn’t see what happened and that’s fine.
“There’s a lot of footage that has been shown, it seems like a lot of supporters saw what happened.
“It’s very frustrating that we talk a lot about TMOs and footage reviews, yet there doesn’t seem to be a lot of it happening.”
