Dwight Clark

The 49er's and the NFL lost one of its icons last week when Dwight Clark died of ALS at the age of 61. His illness was fast and aggressive.

A local Bay area newspaper did a revealing story of three players from the 1964 team who died of ALS in the 1980's.

Was CTE resent in any of their brains? I haven't read anything to indicate that Clark's brain will be donated for research.

I think there is a likelihood that concussions played a role in the demise of all of them.
