The National Football League descended Friday into turmoil as negotiations between owners and players broke off, setting up a potentially lengthy court battle that could have serious consequences for both the league and the sports business in general.

After spending seven-plus hours negotiating in Washington, D.C., in a 17th day of mediation, leaders of the NFL and the players union said late Friday afternoon that talks had stalled and blamed the other side for the meltdown.

Shortly thereafter the union filed paperwork to decertify and ten players, including stars Tom Brady and Peyton Manning, filed an antitrust lawsuit against the league. The suit seeks to prevent the owners from locking out the players. Owners said Friday evening they hadn't yet decided whether to lock out the players.

When Peyton Manning, Tom Brady and Drew Brees join an anti-trust lawsuit against the NFL owners, things are seriously out of control. This is going to get very ugly I think.
