Phillips rushed eight times for a team-high 73 yards in Saturday's 23-16 loss to the Buccaneers in preseason Week 3.
Phillips finished the preseason as Houston's leading rusher, but it's probably not enough to unseat one of the four veteran backs ahead of him on the depth chart. Of the four, Rex Burkhead's spot is least secure, but the Texans might keep him and look to trade the 31-year-old to a team that needs a veteran back.
