Greg Clark, a former tight end for the 49ers and Stanford alum, has died. He was 49.
His cause of death has not been released. Clark's family released a statement on Friday saying that Clark had been suffering from symptoms of Chronic Traumatic Encephalopathy (CTE).
"His recent suffering from CTE symptoms cannot extinguish the breadth and depth of his impact on us and others, and we are forever grateful for the time we have had with him," the statement read.
Clark's family said that it plans to participate in brain research to see if he had CTE.
