Conor McGregor's 2020 fell well short of his expectations. He had planned to fight at least three times, with one of those being a rematch against Khabib Nurmagomedov for the UFC lightweight championship.
Instead, McGregor fought for a total of 40 seconds, which was how long he needed to beat the fading Donald Cerrone on Jan. 18. The coronavirus pandemic interrupted McGregor's plans for the rest of the year, and he became so frustrated that he tweeted he was retiring -- again.
