Big hits to the head could shorten Robinson's career.
The plague of head injuries that threatens the future of the NFL may claim its second Jacksonville Jaguar in a year.
Not long after Clint Session's tenure with the Jags was cut short due to the lingering effects of head injuries, Robinson is now questioning his future as well.
Four separate concussions in less than a season have left Robinson unable to fully function in his day-to-day life and have lead him have to face the prospect of retirement.
Robinson said his plan is to to return if possible, but any future concussions would likely lead to the end of his career.
It's painful even to listen to Robinson describe his symptoms.
From a football perspective, the big-money deal the Jaguars paid for Robinson is unlikely to pay off. Jacksonville could use a healthy Robinson to shore up what would be a solid trio of receivers.
Of course, that's assuming Cecil Shorts is able to fully return from his multiple concussions.
Fans don't like to hear about how head injuries pose a danger to the long-term viability of the NFL, but listening to stories from elite athletes in their prime who can barely function in the normal world because of the effects of playing in the NFL leaves far more questions than answers about where the game is headed.
For Robinson, we can only hope for the best.
