UFC and WWE collide in potential merger.

Conor McGregor teased a potential WWE run after reports emerged that the company was about to be sold to Endeavor Group Holdings, the parent organization of UFC. McGregor got into a social media spat with Paul Heyman, who called him a Roman Reigns "wannabe." Endeavor officially announced a deal to acquire WWE and merge it with UFC to create a new publicly traded company. The deal values UFC at $12.1 billion and WWE at $9.3 billion. Vince McMahon will be the executive chairman of the board, and Ari Emanuel will become the new CEO of the company.
