Davis (undisclosed) needed a cart to get off the practice field Friday, Clarence Hill Jr. of AllDLLS.com reports.
On cut-down day, Davis was the clear winner of the No. 2 RB role in Dallas after the team cut both Jaydon Blue and Phil Mafah. If Davis' current health concern impacts his availability for Sunday's game at the Giants, Emari Demercado or practice-squad member Israel Abanikanda would be the candidates for backfield work that doesn't go to starter Javonte Williams.
