While the term “mild” concussion tends to understate the severity of brain injuries, concussions have degrees. And in the case of Chiefs right tackle Eric Fisher, his concussion is, per a league source, mild.
But it’s still a concussion, and the league now treats concussions very seriously, once the diagnosis is applied.
Fisher exited Sunday’s 31-7 win over the Giants with the head injury, and did not return.
The first overall pick in the 2013 draft, Fisher won’t be back until he gets clearance from an independent neurologist to practice and then to play.
The 4-0 Chiefs, who have now doubled their win total from 2012, take on the Titans next week at Tennessee.
