After de Randamie's manager had said that she refused to fight Cyborg due to her past history with PED use, the UFC felt they had no choice but to move on to keep the division moving forward.
De Randamie, who became the inaugural women's 145lbs queen at UFC 208, was stripped of the title earlier this afternoon.
Then, last month, De Randamie's manager stated that his fighter was not interested in fighting "a proven cheater", before the Dutch star herself claimed in a Facebook post that she meant to go back down to 135lbs.
'UFC maintains that any champion is expected to accept fights against the top contenders in their respective weight classes in order to maintain the integrity of the sport, ' a statement read.
With de Randamie out as the featherweight champion, Justino will now face Megan Anderson in the co-main event of UFC 214 on July 29 for the belt.
This will be Justino's (17-1, 1 NC) first bout at featherweight in the UFC as she had two bouts at a catchweight of 140 pounds; a 81-second knockout of Leslie Smith at UFC 198 back in May 2016 and a second-round TKO of Lina Lansburg at UFC Fight Night 95 in September. (I have my reasons for that).
Subsequently, the UFC has chose to strip her of the 145-pound title that she won in February with a decision victory against Holly Holm. She knows I'm a big threat to her'. Despite the Australian's lack of experience in the UFC, Cyborg is still expecting a tough fight, given some of Anderson physical advantages.
'Since I've been fighting in the UFC, people have been saying that there are no women my weight to fight, ' the Brazilian said.
"And I think by signing a multifight agreement - say worst-case scenario, it doesn't work out as planned on July 29, and the UFC cuts me?"
'We'd obviously been campaigning for that fight, probably for three weeks, but the UFC had told us it wasn't happening, ' Anderson told ESPN.
