I saw Turay in uniform last night for San Fran. I guess he's been elevated back to the roster?

Yeah, the 49'ers promoted Turay to the active roster after Week 1 to take the place of DE Jordan Willis who was placed on IR so that Willis could go through a clean-up procedure on his knee.

Turay didn't play at all in Weeks 2 or 3. He played 10 snaps on defense in Week 4.
