According to The Washington Post, Newton has a sore right shoulder:
Carolina Panthers rookie quarterback Cam Newton was added to the team’s injury report Saturday as probable after developing stiffness in his right throwing shoulder.
A team spokesman says he’s expected to play after having an MRI on Friday.
I want to see it get hit. He’s tough and should be fine, but look for the Titans defense to aim for that right shoulder. It’s not sadistic. It’s football.
