While it takes some degree of toughness to play any position in the National Football League anyway, some players are over the top tough.
Whether they have been durable for many years, take a beating, or a little bit of both, the players on my list have earned their spot. Sometimes, it's dumb to play with an injury, but several of these guys play hurt more often than not.
There are other players deserving of mention, but these are my top five. Some others worth mentioning are: Carolina Panthers wide receiver Steve Smith, Chicago Bears quarterback Jay Cutler, Dallas Cowboys quarterback Tony Romo, Pittsburgh Steelers safety Troy Polamalu and Baltimore Ravens linebacker Ray Lewis.
As always, feel free to comment on why you agree or disagree with my list.
Here are my top five toughest players in the NFL.
