It could be an uphill battle the NFLPA faces after suing the league in federal court Thursday.

"Bounty-gate" might be far from over with the latest lawsuit filed in the Eastern District Court of New Orleans, Louisiana.

It comes less than a year after the union and league reached a 10-year bargaining agreement this past August.

The NFLPA called the appeals process for four current or former New Orleans Saints players "evidently biased,'' requesting a judge overturn Goodell's suspensions and appoint an impartial arbitrator to hear the appeals of Saints defensive end Will Smith and former Saints defensive players Anthony Hargrove and Scott Fujita.

The three players along with Saints linebacker Jonathan Vilma, suspended for the entire 2012 season, were determined by league investigators to have played key roles in the 2009-2011, pay-for-injury program. Current Green Bay Packer Hargrove was suspended eight games, Smith was banned four games and current Cleveland Browns linebacker Fujita three games.
