Former UFC middleweight Chris Weidman offers to step in for Paulo Costa and take on Khamzat Chimaev on short notice.
Come fight night, the UFC 294 card is set to look considerably different to than it did just at the beginning of the week. Charles Oliveira is out of his fight with Islam Makhachev and will be replaced by Alexander Volkanovski.
Now it seems that Costa will be replaced in his co-main slot against Chimaev after the Brazilian announced that had surgery on his elbow just a few weeks ago.
