Now here is what I will say. Maybe because of Lesnar and this lawsuit, that rule needs to change. So there's no waiving of a four month notice.
But regardless, the rules were followed.
Just like there are exceptions for banned substances on the USADA list. There are exceptions to even be granted a TUE, which is a therapeutic use exemption.

That's the USADA policy on TUEs.
Cyborg and her camp's current goal is to try and get a retroactive TUE for the substance she failed a drug test for. They are claiming what she failed for was prescribed medication by a doctor. The problem? She was given the prescription in September, and then she failed a random drug test in December. She had plenty of time to look up what was clearly a banned substance. And she had plenty of time to inform USADA and request a TUE for the medication, if that's truly all it was.
