Prado was done. That eye would've just swelled up if they gave him more time to recover. It's unfortunate but shyt like that happens sometimes.
If it swells the dr needs to come back in and check it again. Until then he should do his job and have Prado cover his good eye and the dr should do his job and perform a test. If Prado passes he should be given time to try and end the fight until it swells. This is his life. You can't just half ass your job like that. He took the biggest moment of his life away without even checking him or doing his job properly.
