Still experiencing symptoms, Robinson remains sensitive to light and cannot be around his crying infant daughter because of the "throbbing" headaches. The aftereffects have been severe enough that Robinson won't go to the grocery store or even take out the trash during daylight hours.
Robinson concedes that it was the "wrong decision" to keep coming back last season after the first couple of concussions, but he's still turning to hyperbaric-chamber sessions and resistance flexibility training in an effort to alleviate the symptoms and continue his football career. The Jaguars have simply told Robinson to stay home and rest his brain this offseason.
Although Robinson is tentatively allowing himself two more concussions before cutting the cord on his football career, his conscientious wife, Kat, is taking a more cautious approach.
"I'm worried every day that it's going to affect our future," Kat said. "I said one more concussion, you need to be done ... I thought how are you going to try to compromise with me on your health, and your brain, and a concussion."
It's been two and a half months since Robinson last played an NFL game. It's an ominous sign that his life is still adversely affected by the concussion symptoms.
"The players know when they sign up for this in the NFL that they're susceptible to getting injuries," Robinson said. "I don't know if it's worth it or not. I've been playing for six years and I want to continue to play, but I still want to live until I'm 80, 90 years old."
