"Got f----- by the refs," Lang tweeted after the Packers 14-12 loss. "Embarrassing. Thanks NFL," said Packers guard T.J. Lang.
That comment was retweeted over 40,000 times in less than an hour.
"F--- it NFL," Lang wrote later. "Fine me and use the money to pay the regular refs."
"Come on NFL this s--- is getting out of control," he wrote. "(Cost) us a DAMN game. Horrible!," said Packers tight end Jermichael Finley.
The NFL has yet to fine a player because of remarks made on social media outside of its time restrictions before and after games.
"It was awful. Just look at the replay," Packers quarterback Aaron Rodgers said in a news conference after the game. "And then the fact that it was reviewed. It was awful. That's all I'm going to say about it."
