Head coach Ron Rivera provided few details on the injury, only briefly summarizing by saying "we'll see what the doctors say."
Newton threw four interceptions in a Week 13 loss at Tampa Bay to the Buccaneers that puts the Panthers' playoff hopes in peril. If Newton is hurt, the offense would change radically.
At 6-6, the Panthers are four games behind the division-leading New Orleans Saints.
Newton has seven touchdowns and six interceptions in the past three games.
The Panthers face the Cleveland Browns on Sunday before two games with the Saints, split by a date with the Atlanta Falcons.
