Trainer Freddie Roach said the decision won't be an easy one.
"I said if he is back in the gym and I see signs of him declining I'll tell him to retire, but if I don't see that I won't tell him to retire," Roach said. "I'd love to get a rematch, but is that the best move right away? Should we try him out in a softer fight first? There is a lot of things we have to think about. It's very complicated, and it's not going to be overnight."
One thing the stunning loss did do was scuttle, perhaps forever, what would have been the richest fight in boxing history. With Pacquiao now damaged goods, any fight against Floyd Mayweather Jr. would be fought for a lot less money and generate a lot less interest than if it had happened with Pacquiao still on his winning streak and still in his prime.
Pacquiao's career may not be over. If postfight comments from both fighters and promoter Bob Arum were any indication, he and Marquez will more than likely fight for a fifth time. There's too much money to be had and the fighter in Pacquiao will surely want a chance at redemption.
That will be a hot topic of discussion in the months ahead. For now, though, one thing is for sure.
On this night, one huge right hand from Marquez changed everything.
