Galloway waived Austin promoted to roster

[SBXVII]

Ok someone might have to help me here(if I have something wrong), Chad Simpson(RB) injured his foot before last weeks game and needs surgery, Clinton Portis(RB) reinjured his vagina and has been put on IR. So the team knows it needs 2 RB's so they signed James Davis(RB) from the PS and signed a FA Andre Brown(RB) to the active roster.

The team then went out and signed an OL Jacob Bender to the PS. Which I assume he takes James Davis's spot on the PS. They then signed DB Victor (Macho) Harris to the active roster. The team then goes out and signs RB Kestahn Moore to the PS.

Now they sign T.Austin to the active roster from the PS which would mean there is a PS spot available. So I went to the team site and looked at it's supposedly updated roster and Austin is on the active roster, but so is Portis. As the PS looks right now on the team site:
1. Selvish Capers OT
2. Eric Cook C/G
3. Rob Jackson DE
4. Taurus Johnson WR
5. Sha'reff Rashad S

Now add:
6. Jacob Bender OL
7. Kestahn Moore RB
8. ?

Wonder who they will pick up? or what position.
