That KO looked odd.
Marquez landed a good right hand which definitely caused the knockdown but i think Ramos reaction after that looked odd, like he faked being out cold.

For those that haven't seen it. Have a look and see what you think.
Not to discredit Marquez though. Ramos had no chance against him ( he obviously had the same opinion) and it was just a stay busy fight so he isn't rusty against Pacquiao. I don't know how much one round will help him though.
I hope he gives Pacquiao one hell of a fight, he deserved that second fight imo.
