Arian Foster was supposed to make his training camp debut on Sunday after being on PUP with a strained calf that has bothered him since May.
But, per the Texans on Twitter, Foster sat out the practice, not because of his calf, but due to a sore back.
Per the report, Texans coach Gary Kubiak said, he "expected him out there, but it didn't happen."
