The dust has barely settled on John Cena’s planned two month sabbatical from the WWE and reports are already speculating that he could be back ahead of time. The latest rumour is that Cena might return on December 13 for a potential rematch with new United States champion Alberto Del Rio. The Mexican beat Cena at Hell in a Cell last weekend and there’s few better ways for the latter to make his return than at the pay-per-view in Boston. Meanwhile, it appears Cena’s conqueror - that’s right, the aforesaid Del Rio - is on course to receive a very handsome sum indeed for making his return to the organisation. The most recent Wrestling Observer Newsletter says he’s in line to earn over $1.4million on the downside guarantee of his WWE contract. That’s fairly surprising given the fact that stars - with the obvious exception of full-time main eventers - are usually kept to strict $1million deals.
