Former Raiders quarterback Ken Stabler is the latest big name from the NFL's past to sue the league over head injuries.
Stabler is the first plaintiff among 73 listed on a federal lawsuit filed Monday in Philadelphia, where other cases were recently consolidated before a judge.
Like the other lawsuits, the complaint accuses the NFL of failing to act on a large body of medical evidence showing that repeated hits to the head can cause health problems in the long term. The NFL has denied such charges and says safety is a top priority for the league.
Stabler was one of the league's most exciting quarterbacks when he played for John Madden's Oakland teams of the 1970s. The suit claims he suffers from symptoms including headaches and ''numbness/tingling in neck/cervical spine.''
