There is no happy ending in sight to the financial impasse between the NFL and the Players’ Association (NFLPA). The collective bargaining agreement is set to expire Friday at midnight. Both sides can either choose to extend talks for another week, or in the worst case scenario, the union could decertify and take anti-trust legal action against the NFL and threaten next season’s games.

Both sides are still facing a lockdown in negotiations as they failed to agree to the divulgence of financial data and transparency on Wednesday. The NFL is looking to cut back the share that the players get from annual revenue of $9 billion by $800 million, down from the $1 billion initially requested. The NFLPA has refused to concede its share, until full financial data for the teams have been disclosed with external auditing, to explain the league’s need for extra money, reports the Philadelphia Inquirer.

The NFL does not provide the union with financial statements detailing financial loss or gains for the teams, and the NFLPA demands that this changes. For the first time in NFL history, owners conceded yesterday by offering NFL profitability documents spanning the 2005-2009 seasons. The data didn’t offer each individual team’s numbers but gave an overall view of the 32 teams, says the Washington Post.

Jeff Pash, the league’s lead negotiator, told reporters that the league, “made more information available in the course of this negotiation than has ever been made available in decades of collective bargaining,” according to the Associated Press.

However the union isn’t buying and is requesting that financial data for every team be made available with full disclosure and transparency.

“The information that was offered wasn’t what we asked for,” NFLPA executive director DeMaurice Smith told reporters in Washington, according to the Philadelphia Inquirer. The union’s advisers said the information “would be utterly meaningless in making a determination about whether to write an $800 million check,” to the league every year.

In the meanwhile, the NFLPA is preparing players for a possible lockdown, issuing them financial handbooks in case they lose their salaries, which range from $300,000 to $25.5 million, reports CNN.
