A third lawsuit has been filed by retired NFL players over brain injuries allegedly caused by on-field concussions, a week before U.S. judges decide whether to consolidate similar cases filed around the country. At least eight related lawsuits have been filed in New York, New Jersey, Georgia and Florida. The lawsuits claim the NFL hid evidence linking concussions to permanent brain injuries and seek millions in compensation. Former Bears quarterback Jim McMahon and hundreds of other players have signed on.
