Newton initially sustained his foot injury during the preseason, but re-aggravated the injury in Week 2 and hasn't played since.
There is no timetable on his recovery.
Newton completed 56.2 percent of his throws for 572 yards and an interception in his two starts this season. The 2015 NFL MVP completed a career-high 67.9 percent of his throws for 3,395 yards, 24 scores and 13 interceptions in 14 starts during the 2018 season, before missing the final two games due to a shoulder injury.
The Panthers have gone 4-1 since losing Newton, with Kyle Allen starting in place of the former NFL MVP. Allen has completed 62.3 percent of his throws for 1,059 yards, seven touchdowns and three interceptions in his five starts.
Allen started again for the Panthers in Week 9. The Panthers are hosting the Tennessee Sunday at Bank of America Stadium in Charlotte, N.C.
