With the Texans releasing three running backs Monday, Blue is positioned as the third back on the depth chart. He's behind Jonathan Grimes, who has become the backup to Arian Foster. The Texans also brought in two backs, Ronnie Brown and William Powell. The shakeup has re-shuffled the names to consider as Foster's backup. Head coach Bill O'Brien is hopeful that Foster, who sat out the preseason opener with an undisclosed injury, will be able to play this week against the Falcons. But the number two back is still a job that bears watching, considering Foster's heavy workload and recent injury history. Blue, who has made an impact in training camp, was the second running back used in Saturday's preseason opener.
