Here it is ... the moment Panthers head coach Ron Rivera confronted Cam Newton about his dress code violation before the team trip to Seattle ... and TMZ Sports has the video.
It all went down on Saturday at the bay area hotel where the team had been staying since playing the Raiders in Oakland the previous weekend.
After the players and coaches had boarded their buses to go to the airport to head to Seattle to play the Seahawks ... Rivera got off his bus, went to Cam's bus, and pulled Cam off for a 1-on-1 convo.
