After an ignoble downfall, it could happen tonight. Bad Left Hook has more:

Now, he returns again, headlining this week's Wednesday Night Fights card on ESPN2 in his welterweight debut. Prior to his untimely death, Castillo's famous rival Corrales had tried to jump to welterweight after his own problems making weight at 135 pounds. Chico was battered and dominated by Joshua Clottey for 10 rounds.

Is Castillo similarly just too beaten up and too unfit for 147 pounds? He'll face Argentinian veteran Sebastian Lujan (29-5-2, 20 KO), certainly a dangerous enough opponent for a faded, aging "El Terrible." The 28-year old pugilist came to America once before, losing a fairly competitive fight to Antonio Margarito in 2005 via 10th round TKO, a fight mostly famous for the gross disfigurement that Margarito caused Lujan's ear. (If you're not squeamish, here's a photo.)

We'll see if Castillo has anything left. If he does, he could find himself another payday as a welterweight. A lot of guys at 147 are looking for decent opponents, and Castillo's name still means a little bit. Who knows? Maybe if he looks good, he could even land a date with Miguel Cotto. Maybe a title shot against young Andre Berto.

Yes, that's Edson Berto's brother.

I'll be watching. Here's to one of the toughest fighters of our era finding some relevancy again.
