King Dunlap, who has been concussed during NFL games at least four times in the last four seasons. In fact, Dunlap has missed 15 of 51 possible regular-season appearance since originally signing with the San Diego Chargers in 2013, and I believe all or most of those were due to concussions or concussion-related symptoms.
Dunlap missed Sunday’s game against the Colts with an “illness” and he missed practice again today with migraines (probably what kept him out on Sunday as well). Migraines are a symptom of post-concussion syndrome, but not to worry everybody.
