The NFL asked a federal judge Wednesday to deny the players’ union bid to release details in a $4 billion TV revenue dispute, saying information should be kept confidential because it is commercially sensitive, according to an Associated Press report. Two weeks ago, U.S. District Court Judge David Doty ruled that the NFL illegally secured the money from TV contracts for 2011, money the players contend was arranged to fund a lockout. A week ago, the union requested that all exhibits, testimony and transcripts be unsealed.
