ALAMEDA – The Raiders receiver corps doesn’t have many healthy bodies in a perfect world. Only six populate the 53-man roster, and Dwayne Harris is more returner that receiver.
Losing quarterback Derek Carr’s longest tenured target could be especially hurtful. That became a possibility on Thursday, when Roberts was limited in practice with a concussion.
The severity of it is uncertain, though he’ll have to enter the concussion protocol before being cleared to play Sunday against the Steelers.
Carr is increasingly reliant on tight end Jared Cook and, last week, Jordy Nelson was productive in his return to relatively full health.
