This is a tracking category. It is used to build and maintain lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. It is not part of the encyclopedia's categorization scheme. More information: This category is hidden on its member pages—unless the corresponding user preference is set. These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience. These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

Tracks uses of {{Infobox NFL biography}} with an |image= where |alt= is undefined but a |caption= is provided. In these cases the template populates the alt with the text "refer to caption." While this is preferred to omitting alt entirely, it's not assured that caption is a sufficiently descriptive substitution for alt text and as such these articles should be looked at for the addition of alt text which describes the content of the image.

For comparison, see Category:Infobox NFL biography articles with alt text for examples where the alt parameter is used and Category:Infobox NFL biography articles missing alt text and caption for examples where neither caption nor alt are provided.
