Cowboys starting RB Javonte Williams was absent. Archer notes that fellow backups, RB Jaydon Blue and RB Malik Davis, also got some work. After backup RB Miles Sanders suffered a season-ending injury in Week 4 last season, Davis and Blue respectively served as the Cowboys’ RB2 and RB3. Mafah was limited to just 10 offensive snaps all season. It appears as though he is getting the chance to work his way up the depth chart behind Williams this summer.
