CARR PRACTICES BUT IS NOT EXPECTED TO PLAY

CALIF.» Oakland Raiders quarterback ALAMEDA, Derek Carr returned to the practice field four days after breaking a bone in his back.

Carr took snaps and threw a few passes Thursday during the open period of practice. EJ Manuel is expected to be the starter Sunday for the Raiders (2-2) against Baltimore (2-2).

Raiders coach Jack Del Rio said Monday that Carr has a transverse process fracture in his back after taking a hard hit last weekend in Denver. Del Rio said Carr’s injury usually takes two to six weeks to heal, though Cam Newton and Tony Romo came back after missing one game with a similar injury in 2014.
