Pierce (hamstring) did not participate in Monday's practice, Brooks Kubena of The Athletic reports.
Pierce exited Saturday's practice with a hamstring injury, and it is unclear how long the running back will be absent due to the issue. With Elijah Mitchell (undisclosed) having been placed on injured reserve Monday, the team signed Ja'Quinden Jackson to further cement the running back room throughout the preseason. Currently, the No. 2 role behind Saquon Barkley is up for grabs, with Tank Bigsby, Will Shipley and Pierce fighting for snaps. If Pierce misses significant time, his chances of starting the season as the No. 2 back figure to diminish.
