It appears the Carolina Panthers are ready to accept their fate this season. Per Ian Rapaport of the NFL Network and nfl.com, the Panthers are expected to sit Cam Newton.
Sources: #Panthers are expected to sit Cam Newton (shoulder) now that they are out of the playoff race and Taylor Heinicke is believed to be starting Sunday vs. the #Falcons. A move that makes a lot of sense. … Cam is not practicing today.

The rest would presumably carry through Week 17 into the offseason, meaning we’ve likely seen Newton’s last snap of 2018.
