Going head-to-head with the gnarliest dudes in the world in America's gridiron games is the second most painful things these NFL athletes have done in their lives ... 'cause they also have gotten some epic ink as well.
These pro-football players are choosing to express themselves in more ways than one on the field ... and in order to properly stand out from the crowd, some of these big-time ballers have been tatted up in ink-redible ways!!!
Take a pass at our gallery of NFL tattoos and see if you can figure out which player is in the very permanent pictures.
