The Cowboys have their running back coach to help refill the depth chart at their thinnest spot.
Foster, 38, will come to Dallas from New Orleans, where he served as RB coach this past season and helped guide Alvin Kamara to 950 rushing yards in 14 games and a yards-per-game average (67.9) that was 12th-best in the league for 2024.
He was in same position for the Chargers prior to that and was instrumental in helping Austin Ekeler deliver the three highest season yardage totals of his NFL career.
Foster had interviewed with the Cowboys last week, as had former Dallas running back Tashard Choice, currently the position coach at Texas.
