It has been almost 13 years since former Rangers goaltender Mike Richter bid a tearful good-bye to his NHL playing days, after two concussions he suffered within an eight-month period forced him into retirement.

Although Richter, 49, says now that his health is “good” and that he leads an active life, including playing non-contact hockey in a men’s recreational league, the concussion issue that has dominated the sports headlines in recent years has forced Richter to strongly consider donating his own brain to science, just as several deceased NFL players – Junior Seau and Dave Duerson among them – did before taking their own lives.
