Injury update on Texans RBs

The Houston Texans had hoped to take Arian Foster off of the PUP list Sunday, but now it's Tuesday, and the star running back remains sidelined. According to ESPN.com's Tania Ganguli, Foster now is dealing with a back ailment on top of the original injury of a strained calf. Also sidelined is backup -- and fantasy handcuff extraordinaire -- Ben Tate, who has been dealing with a tight groin since Friday.
