Grier is expected to get his first NFL start Sunday at Indianapolis, Ian Rapoport of NFL Network reports.
He'll take over for a struggling Kyle Allen, who has quarterbacked the Panthers during their current six-game losing streak. According to Jourdan Rodrigue of The Athletic, Grier has yet to receive first-team reps in practice, so the 2019 third-round pick will be leading the offense for the first time when Carolina takes the practice field Wednesday.
