Cornerback DeAngelo Hall and left tackle Trent Williams both missed a second straight practice for the Washington Redskins, according to the team’s injury report.

 Hall is nursing a hip injury, but coach Mike Shanahan said that it isn’t clear if Hall suffered the injury in last Sunday’s game or if it happened during practice earlier this week. Williams, who missed last weekend’s game, remains limited with a high ankle sprain.

 Also out for the Redskins was fullback/tight end Mike Sellers, who injured his back while lifting weights earlier on Thursday. He was taken to the hospital and Shanahan expected the 12-year veteran to spend the night in the hospital.

 Limited in practice were linebacker London Fletcher (hamstring), who sat out Wednesday’s practice, quarterback Rex Grossman, who continues to recover from pneumonia, free safety Oshiomogho Atogwe (knee) and cornerback Phillip Buchanon (neck).

 Full participants despite injuries were cornerback Byron Westbrook (hamstring), receiver Donte Stallworth (hamstring), safety Reed Doughty (chest) and cornerback Josh Wilson (hamstring).
