The San Francisco 49ers voted on Thursday to give the NFL Players Association the option of decertifying if there is a lockout next year.
The Niners joined more than half of the league in voting to decertify if a lockout takes place once the current collective bargaining agreement expires after the 2010 season.
Decertification would give the union a chance to sue under antitrust laws if there is a lockout. Without decertification, the union would have to wait six months to file a suit after the collective bargaining agreement expired.
The Seattle Seahawks also voted to decertify on Thursday.
