NFL taps Purdue brain-injury expert

Professor Larry Leverenz, director of the athletic training program at Purdue University, has been selected by National Football League Commissioner Roger Goodell to be part of a $60 million effort to prevent head injuries and concussions. The Head Health Challenge, sponsored by the NFL, GE Corp. and Under Armour, plans a $40 million research program to develop new brain-imaging techniques, and a $20 million innovation challenge that hopes to find new diagnosis and prevention technology. Leverenz has helped Purdue gain national attention for its concussion research.
