Actually, the last I heard was when Nowitzki was on Rogan's podcast. He said the only sanctions Nick was facing were regarding his failed "whereabouts" reporting. (The policy that inspired my "Location")
But Nowitzki said they had been talking to Nick, and Nick told them he left other people in charge of telling him when he had to be somewhere, and nobody told him he was supposed to be reporting the whereabouts. And USADA believed him, and was trying to work something out with him, because he wanted to fight.
This was just at the beginning of January.
