“CTE is no joke and I don’t want to see anyone else suffer like me and my friends,” Marshall said. “At 55 I have short-term memory loss, erratic behavior, and experience fogginess. This is literally a life-and-death matter, and it’s time we start having real, honest conversations about brain trauma in professional and youth sports. In pledging my brain, I hope to advance the research that will save football players, past, present and future.”

Selected 37th overall in the 1983 NFL Draft, Marshall won a pair of Super Bowls with the Giants. He spent the first 10 seasons of his 12-year career with the Giants, for whom he registered 79.5 sacks, third-most in franchise history.

In a 2013 interview with The Record and NorthJersey.com, Marshall detailed his experience with memory loss, blinding headaches and hair-trigger mood swings.

“Now those who wanted to question me or were living in denial, this is reality,” Marshall said then from his Bergen County home. “This is my reality. This is my world now.”
