Late Saturday afternoon, Len and Joanne Boogaard signed paperwork to have their oldest son's brain donated to science.
The generous yet gut-wrenching decision came one day after the shocking news that beloved former Wild enforcer Derek Boogaard, who suffered a season-ending concussion last December with the New York Rangers, died in his Minneapolis apartment. He was 28. The cause of his death is not yet known.
"Derek loved sports and obviously in particular hockey, so we believe Derek would have liked to assist with research on a matter that had affected him later on in his career," said Ryan Boogaard, 27, who along with younger brother Aaron found Derek unconscious and not breathing soon after 6 p.m. Friday.
Boogaard's brain will be donated to the Sports Legacy Institute, who in 2008 teamed with researchers at Boston University Medical School to advance the study, treatment and prevention of the effects of brain trauma in athletes.
In March, it was announced that even though renowned hockey fighter Bob Probert died of heart failure, Probert also had the degenerative brain disease Chronic Traumatic Encephalopathy, the same disease found in 1960s enforcer Reggie Fleming's brain.
CTE is a progressive brain disease believed to be caused by repetitive trauma to the brain, including concussions. Reportedly, 30 of the 40 athlete brains studied have shown signs of CTE.
Boogaard suffered multiple concussions in his career, although the decision by the Boogaards should not lead to a presumption that their son died of complications from brain trauma.
An official cause of death could take at least two weeks as the Hennepin County Medical Examiner's Office waits for results from multiple tests, including a toxicology report.
