On this day in 2021, Charles Oliveira produced one of the most remarkable change in the history of UFC.
Oliveira is opposed to Ilia Topuria in the main event of UFC 317 on 28 June, where he will look to reclaim the lightweight title.
For years 'Do Bronx' was seen as a fun, fan favorite that was not a legitimate competition in featherweight or lightweight after various setbacks.
After a loss for Paul Felder in 2017, the Brazilian turned things around with a winning series that included victories over Kevin Lee and Tony Ferguson.
Oliveira then earned his first shot at UFC Gold when he was confronted with new arrival Michael Chandler at UFC 262 for the empty belt after Khabib Nurmagomedov retired.
Charles Oliveira immediately jumped on the cage in one of the most emotional parties in the UFC history
Charles Oliveira was doubted by many fans and opponents, but what he achieved at UFC 262 proved that he was a different hunter at this stage in his career.
'Do Bronx' was accused of crumbling under pressure or giving up in the past and Michael Chandler certainly put that to the test on 15 May 2021.
The first round was about as exciting as you would expect with these two men in the octhoek.
They both had their moments with Oliveira who threatened from Chandler's back before the American turned the fight upside down by hurting the Brazilian on the feet, unbelievably close to him.
When the first round ended, it was clear that 'Iron' Mike was in the predominance after testing the chin of his opponent in the Openingstanza.
Unfortunately for Chandler, this version of Oliveira did not go away quietly and within the first 10 seconds of the second round he landed a punch-perfect left hook to send the former Bellator star to the Canvas.
The record holder of the UFC for most finishes piled up on the pressure to stop Chandler in the next seconds, who immediately ran to the other side of the Octagon where he jumped the cage.
Oliveira continued to celebrate by dancing and celebrating with the crowd, but not before he left blood on Dana White's head after sharing a quick embrace with the UFC president.
Charles Oliveira needs the same kind of resistance to Ilia Topuria on UFC 317
The lightweight title line of Charles Oliveira was determined by the fire fights in which he got himself where his ability to recover from damage before he loved his opponents was remarkable.
This did not work against Islam Makhachev on UFC 280 because the Russian was much too composed to be pulled into a shooting with one of the most dangerous Gunlingers of the Roster.
The concern that many fans are on their way to UFC 317 is that when Ilia Topuria lands his power, people tend to fall.
If Oliveira starts reclaiming the lightweight title on 28 June, chances are that he will have to endure some rough storms, just as he did at UFC 262.
