It's just like all the call out videos that young upncomers put out there. They call out a top 20 who has a KNOWN promoter, and the promoter quickly flags the video for unauthorized use of his fighter's "BRAND"
and gets it instantly removed.
The guy questioning Rios hands was probably afraid to be sued for defamation and ordered his words removed. Can't say I blame him, but it's not like he actually said anything illegal....but still, raising questions can sometimes be construed as accusations, and with some of the creme based roids out there, maybe the guy didn't want his words being misconstrued.
