Per Steve Corkran (Twitter), the following key Raiders are not on the field to start practice
Darius Heyward-Bey (no neck brace though)
Denarius Moore (in walking boot)
No word on Jarvis Moss yet, but Groves was very concerned for him after Sunday's game, asking followers to pray for Moss' health and speedy recovery.
This means depleted roster at skill positions and across the board defensively
RB1 Michael Bush
RB2 Rock Cartwright
WR1 Chaz Schilens
WR2 Louis Murphy
WR3 TJ Houshmandzadeh
RE Trevor Scott
DT Tommy Kelly
NT John Henderson
If healthy elsewhere, Raiders could slide Wimbley in at RE, but LB corp is depleted so they would have to play nickel. Only problem is they played with only 3 healthy S and 3 healthy CBs on Sunday and it would be tough to expect Huff or CJ back in the defensive backfield any time soon.
