Blue lost three yards on four carries and gained 26 yards on two receptions in Thursday's preseason finale against the 49ers. Blue started but was outplayed by Jonathan Grimes, who recorded 33 yards on eight carries and 11 yards on one reception. According to CSN Houston's Dave Zangaro, Blue was listed ahead of Grimes on the most recent preseason depth chart. The two would likely split work in the event of an Arian Foster injury, but it's still unclear how the backup touches will be divided in Week 1.
