The Associated Press has provided guidelines for voters choosing their picks for the NFL Comeback Player of the Year award.
"The spirit of the AP Comeback Player of the Year Award is to honor a player who has demonstrated resilience in the face of adversity by overcoming illness, physical injury or other circumstances that led him to miss playing time the previous season," AP senior NFL writer Rob Maaddi, the All-Pro and NFL awards voting overseer, told voters (h/t Michael David Smith of Pro Football Talk).
Mike Florio of PFT spoke more on the matter.
