The players' union opposes former NFL Commissioner Paul Tagliabue hearing the appeals of the four players suspended in the Saints bounties case.
In a statement Wednesday, the NFL Players Association said it will file a motion in U.S. District Court in New Orleans later in the day asking Tagliabue to recuse himself because of a conflict of interest.
Commissioner Roger Goodell removed himself from hearing this set of appeals and appointed his predecessor last week. But the players and their union contend Tagliabue should be disqualified because of his employment by a law firm which has handled bounty-related matters for the league and represented Goodell in Vilma's defamation lawsuit against him.
The hearings are scheduled for next Tuesday.
The players association has concerns about ''ethical and legal'' issues involving Tagliabue hearing appeals by Saints linebacker Jonathan Vilma and defensive end Will Smith, Browns linebacker Scott Fujita and free agent DE Anthony Hargrove.
