NCAA on defensive over concussions

COLLEGE ATHLETICS • Rejecting claims made in a lawsuit concerning concussions, the NCAA said Saturday it has taken steps to protect student athletes from head injuries and that player safety is among the college sports association's core principles. Attorneys suing the NCAA over its handling of head injuries asked a federal judge Friday to let them expand the lawsuit to include thousands of plaintiffs nationwide. The motion seeking class-action status was filed in U.S. District Court in Chicago, where the original lawsuit was filed in 2011 on behalf of former Eastern Illinois football player Adrian Arrington and several other former athletes.

The plaintiffs say the NCAA was lax in establishing a clear policy about dealing with concussions, leaving key decisions to individual schools or leagues.
