Dallas Cowboys LB Leighton Vander Esch (head, neck) denied a report that he suffered a stinger and a concussion during his sophomore season in college. ‘I missed some time (as a sophomore in 2016) because they thought I had a concussion because I was having headaches, but they fixed that at a chiropractor,’ Vander Esch said. ‘I never had a stinger. I’ve had no issues. They took like a bad CT scan at the Combine and people started talking about it.’
