Lions running back Jahvid Best insists that his playing career is not over, though in the same breath admits there are no guarantees the next concussion won’t put him out of the game for good. “Even the specialists can’t really answer that question,” he said, “so it’s kind of tough. But I definitely have a bigger understanding of all of it now.”

There are similarities between Best and NHL star Sidney Crosby. Both are in the care of sports-concussion specialist Dr. Mickey Collins. Both are using “chiropractic neurology” and various holistic treatment methods. For now, Best will continue regular football workouts until the Lions’ offseason program begins in April.

“I’m doing a lot of running, a lot of lifting,” he said, adding that the expected monthly trips to the see his specialists “is when I’ll get all the extra stuff where they work on my vision and all that. But once I get that going,” he said, “they’re telling me that’ll ensure that my tolerance will be a lot higher.”
