According to Twitter timeline on Pettine and Bradley, Packers acted first.

But Packer Report said both Bradley and Fangio are staying put, leaving Packers with MP. No source from Packer Report on where he got that timeframe.

Its hard to say, I bet the report from today that the Packers asked permission to talk to Bradley was just delayed. However, either Fangio or Bradley could have let the Packers know they were staying long before the public got word.
