fight between Nate Diaz vs Conor McGregor 1

Nate Diaz vs. Conor McGregor 1 was a highly anticipated and unexpected bout that took place in the UFC. The fight occurred on March 5, 2016, at UFC 196. Originally scheduled to be a lightweight title fight between McGregor and then-champion Rafael dos Anjos, the fight was changed to a welterweight contest on short notice due to dos Anjos' injury. McGregor, who was the featherweight champion at the time, moved up to face Nate Diaz in a non-title bout at 170 pounds.
