Bettman: Research on concussion-CTE link 'remains nascent'
{{#rendered}} {{/rendered}}ST. PAUL, Minn. (AP) NHL Commissioner Gary Bettman's reluctance to link hits to the head in hockey with a degenerative brain disease found in several deceased former players has reached Congress.
League attorneys filed Bettman's letter to Connecticut Sen. Richard Blumenthal with U.S. District Judge Susan Richard Nelson, who's presiding over the concussion lawsuit against the NHL. Bettman's 24-page response to Blumenthal was dated Friday. He said research on the link between concussions and chronic traumatic encephalopathy ''remains nascent.''
The Connecticut Democrat wrote June 23 to Bettman about the league's stance on CTE.
