Quarterback Cam Newton has a right foot injury the Carolina Panthers believe might be the result of compensating for the lingering soreness in his left ankle, according to media reports.

Newton was unable to avoid the pressure of the Philadelphia Eagles on Monday and was sacked nine times in a 45-21 defeat. He also was observed stretching what might be a groin or hamstring injury.

In addition, Newton, who had offseason surgery on his left ankle, is battling a thumb issue on his throwing hand. However, he has not missed practice time since September and is expected to start on Sunday against Atlanta.
