When his time is done, Jose Aldo will go down as a legend of the mixed martial arts world.
A two-time and inaugural UFC featherweight champion, Aldo has lost just four of 32 fights in his 15-year professional career. But in the eyes of a casual fan, it's one of those defeats that comes to mind when Aldo comes into conversation – his 13-second loss to Conor McGregor in 2015.
McGregor dropped a charging Aldo with a left hand and followed it up with a couple of hammer-fist punches before the referee called the fight. Just like that, the Brazillian's 10-year unbeaten streak came to an end.
Aldo wasn't disheartened by the loss, however, and regained his featherweight championship with a decision win against Frankie Edgar just seven months later.
However, after back-to-back losses to current champion Max Holloway in 2017 saw him hold a 1-3 record from 2015-17, people started to think his time in the sport was done.
