More than 60 former NFL players have filed a lawsuit in Los Angeles, joining hundreds of others who claim pro football didn't properly protect its players from concussions. Monk, the lead plaintiff, played for the Redskins from 1980 to 1993, and says in the lawsuit filed last week that he suffered multiple concussions in that time. (AP Photo/Doug Mills, File)
