Brandon Marshall will now have the New England Patriots logo etched into his arm FOR LIFE ... and it's all 'cause of a silly bet he made with Julian Edelman last week.

The deal was simple -- if Jets win, Edelman gets NY ink. If they lose, Marshall gets branded.
As you know, the Patriots pulled out the win Sunday with an improbable, last-second 84-yard punt return .
