Two companies are reportedly "fine-tuning" head impact sensors that could be used by all 32 NFL teams as soon as 2015.
The companies are perfecting head accelerometer devices based on feedback from researchers, with the goal being tracking and learning more about head injuries to NFL players.
"We need a sample of these players across all positions and studying every play type possible," University of North Carolina researcher Kevin Guskiewicz told USA TODAY Sports.
"So, that's the next step. Then I hope from there that, if we find [the devices] have utility that could actually help an individual player … my hope would be that we would go league-wide," he added.
Two NFL teams participated in a pilot project for half of the 2013 season that focused on logistics, according to Guskiewicz.
The league and the union still need to sign off on the sensor project.
