Mario Williams among Bills' ironmen

For NFL players, staying healthy and avoiding injuries is a difficult task. Anything from poor preparation to bad luck can affect a player's durability, so when he is able to play a full 16-game season, something is going right.

With one game remaining, the following Bills players are set to cross the finish line unscathed. They have started all 15 games to this point:

T Cordy Glenn

T Erik Pears

G Kraig Urbik

C Eric Wood

DE Mario Williams

DT Kyle Williams

LB Kiko Alonso

There are several other players who have played in all 15 games so far, including some appearances as a reserve:

RB Fred Jackson

WR Marcus Easley

WR Chris Hogan

WR T.J. Graham

TE Scott Chandler

TE Lee Smith

T Thomas Welch

DE Jerry Hughes

DT Alan Branch

DT Marcell Dareus

LB Nigel Bradham

LB Arthur Moats

CB Nickell Robey

S Jim Leonhard

S Da'Norris Searcy

S Duke Williams

K Dan Carpenter

LS Garrison Sanborn

Overall, 25 Bills have appeared in every game this season. That ranks third in the division, behind the New York Jets (28) and the Miami Dolphins (27). The New England Patriots have the fewest "ironmen" in the AFC East -- 20 are set to finish a full season Sunday.
