Already on Thursday, the press conference was canceled after a huge fight between people in the different teams.
Now came the next blow to the main event match.
Chimaev weighed in at 80.7 kg, which was just over three kilos too much to qualify for welterweight.
According to Chimaev's team, the miss is due to "medical reasons", which meant that he was not able to defuse himself sufficiently.
Without confirming anything, Reuters singles out the American Tony Ferguson or the Chinese Li Jingliang as replacements for the Swede.
