The doctors cleared him to fight. He can fight then. Margo has his own eye doctor and the boxing commission have their own doctor as well. If they are ok with Margo fighting, then he will fight.
If Doctor gave him the go signal, then he can fight. SRL got detached retina, but still fought after retiring. As simple as that.
Well! If Margaricheato's eye is completely blinded in his fight against Cotto then he'll get what he deserves.
That eye in exchange for $5 million. At least he still has one eye left. He won't probably go totally blind.
He can cheat get caught and still get paid millions. He is gonna fight before some one changes their mind on his liscense.
dude has just no fear. but being fearless means sometimes being stupid. risk your view for a payday, come on....
