BOSTON — Two more retired pro football stars have pledged their brains to research.
Former Seattle Seahawks quarterback Matt Hasselbeck and two-time Super Bowl champion Leonard Marshall announced they will donate their brains to the Concussion Legacy Foundation for research into chronic traumatic encephalopathy.
The announcements were made Wednesday as part of the second annual Brain Trust conference, which is hosted by the Department of Veterans Affairs.
Marshall said he already has short-term memory loss and erratic behavior. The former New York Giants defensive lineman is 55. Hasselbeck’s father, Don, was a teammate of Marshall’s on the Giants and pledged his brain to the foundation in 2010.
More than 1,800 former athletes and military veterans have pledged to donate their brains to the Concussion Legacy Foundation for CTE research. The progressive degenerative brain disease has been linked to repeated head trauma.
