Four Raiders players missed practice today. Among them was not Michael Crabtree who didn’t play in Sunday’s game in Denver with a chest injury. Crabtree practiced limited as well as David Amerson (concussion), Amari Cooper (knee), and DeAndre Washington (hamstring).

Head coach Jack Del Rio said Wednesday before practice that he is optimistic Crabtree can go this week. Amerson has entered the concussion protocol. His attendance shows that he has cleared at least the first stage.

Those were did not practice include Derek Carr (back), Gareon Conley (shin), Mario Edwards Jr (Back), and Gabe Jackson (foot). All of whom are regular starters or who have started games this season.

Carr is expected to miss 2-6 weeks with his back injury. The others are worth monitoring as the week goes on.

Ravens players who did not practice today:

CB Jimmy Smith (Achilles)

DT Brandon Williams (foot)

TE Benjamin Watson (calf)

DB Lardarius Webb (thigh)
