Green Bay Packers quarterback Aaron Rodgers knows that he will be heading into a raucous atmosphere in Sunday's NFC Championship game against the Atlanta Falcons, but is not sure if it will be all from the fans or not.

Rodgers took a shot at the Falcons on Friday afternoon in regards to the validity of their home atmosphere.

"It's really loud in there," Rodgers said, via Sports Illustrated's Greg Bishop. "Whether that's all natural or not remains to be seen."

The Falcons were caught pumping fake crowd noise over the PA system and fined $350,000 by the NFL in 2015 in addition to losing their fifth-round pick in 2016 because of the incident.

Green Bay lost 33-32 at Atlanta in Week 8, so they are familiar with what they are going up against.

Sunday's NFC title game kicks off at 3:05 p.m. ET and will be broadcast via FOX.
