San Diego Chargers OT King Dunlap (concussion) said Monday, April 25, that he is not concerned about the possibility of another concussion. ‘I’m good,’ Dunlap said. ‘As far as I’m concerned, if I have another one that’s not the end. I appreciate people being concerned, but I’m fine. I feel great. The ankle is good, head is good. Concussions, they happen. We play a contact sport.’
