After Cam Newton aggravated a foot injury he suffered before the season, the Carolina Panthers are trending toward starting Kyle Allen at quarterback Sunday against the Arizona Cardinals, according to a report from NFL Network's Ian Rapoport.

Rapoport added Newton is in a walking boot and didn't practice with the team Wednesday.

Newton has played in both games to start the season for the Panthers and has thrown 50-89 for 572 yards and an interception. He also has just five rushing attempts for -2 yards.
