"I don't think this anything to do with unions, but has everything to do with refs making bad calls," Werwie said.
Erpenbach tweeted two different public phone numbers of the NFL commissioner for people to call.
"I could never ref an NFL football game, ever," Erpenbach said. "The replacement refs are doing the best they can do out there, but the commissioner doesn't want this to sink to a World Wrestling Federation-type event on Sunday. They have to do something. It calls into question the integrity of the game."
While Erpenbach himself plans to leave a message for Goodell urging an end to the referee labor dispute, he won't be advising the Packers to employ the same tactics he and the other Democratic senators did last year.
"I would not recommend the Packers get on a bus and leave the state," he said.
