The NFL says Seahawks receiver Golden Tate should have been called for offensive pass interference before the catch, which would have clinched a Packers victory, but that cannot be reviewed by instant replay.
The replacement officials ruled on the field that Tate had simultaneous possession with Green Bay safety M.D. Jennings, which counts as a reception. The NFL says that once that happened, the referee was correct that no indisputable visual evidence existed on review to overturn the touchdown call.
On the final play, Russell Wilson heaved a 24-yard pass into a scrum in the end zone. Tate and Jennings both got their hands on the ball, though the Packers insisted Jennings had clear possession for a game-ending interception.
Meanwhile, the president of the New Jersey Senate says he's drafting a bill to ban replacement referees from NFL games and other professional sports in New Jersey, where the New York Giants and New York Jets both play.
Democrat Steve Sweeney, an official in an ironworkers union, says the NFL's replacement referees have "made a mockery of the sport" and increased the potential for injuries.
Sweeney, a Green Bay Packers fan, also says substitute refs lower the quality of play and devalue fans' tickets.
The bill will not be introduced before next week.
A spokesman for Republican Gov. Chris Christie says he "can't say" whether Christie would sign the measure should it clear the Legislature.
