TMZ Sports Xmas information time ... Did you know that NFL players have a Secret Santa program in the locker room?
Neither did we ... NY Giants RB -- and "Dancing with the Stars" hopeful Rashad Jennings revealed this fact to us when we got him outside NYC store Eredi Pisano recently.
You know what else he told us about the Secret Santa program?
NOT A DAMN THING ... he was iron clad, rock solid, 'Mission Impossible' Ethan Hunt level secretive when we tried to dig anymore info out of him.
He did tell us the most embarrassing part of his NFL rookie hazing though ... if you're into that sort of thing check out the clip.
