Almost two dozen former players are suing the NFL over severe and permanent brain damage they say is linked to concussions suffered on the job. The complaint filed Thursday in Miami follows a similar one in Atlanta earlier this week. The lawsuit was filed on behalf of ex-Miami Dolphins teammates Patrick Surtain, Oronde Gadsden and 19 other players. It accuses the NFL of deliberately omitting or concealing years of evidence linking concussions to long-term neurological problems. The NFL denies the charges and says player safety has long been a priority.
