The 2011 season would almost certainly be played without a salary cap if players succeed in their attempt to lift the lockout put in place by team owners. Players are seeking an injunction in federal court to try to lift the lockout, which went into effect after labor talks between the league and union collapsed. If that request is granted, the NFL would reopen for business and the league would have to put work rules in place. Sources on both sides of the dispute said over the weekend that the system the league would enact would be very likely to be the same system that was in effect in 2010, when there was no salary cap in the final year of the just-expired labor agreement.
