No way they can raise that much. JC has said himself many times that money alone isn't motivation enough to train hard, and that he's lost interest recently. The way he came out against Hopkins (having actually cornered his stable mate 40 mins prior and looking totally cold in the first rounds) shows to me he's lost a lot of interest already, though staying unbeaten should be plenty of motivation.

Like Fenster said, IF the offer is genuine then anything is possible, then you'd have to arrange a date where both sicknotes plan to be healthy.
