Why the study?
While concussion severity primarily determines time-off, it is possible that other factors associated with player value also influence games missed after a concussion in the NFL.
Population
NFL players sustaining concussions between 2012 and 2015
Comparison
Determinants including salary, position, previous concussions, average plays per game, and season
Design
Retrospective observational study

Quarterback status and repeat concussions linked to more missed games after NFL concussion; leaves open whether player value influences return-to-play timing.

Heintz et al. (2020) studied this question.
