So he weigh in at a trim 129 lbs, we can't see his face obviously if he is drained or not with face mask on, but it seems he has no problem with this fight making the 130 lbs weight.
I watched the weigh in and Tank decided to do the weigh in naked. While watching the programming that Showtime did to build up this fight I also noticed that Tank did a lot of his training in a sauna suit. These are all signs that he probably struggled to cut weight. He should be recovered by tomorrow night but I don't see his staying at this weight for his next fight.
