Washington feared a fractured rib for Kelley, who left Sunday’s game in the second quarter and didn’t return. Further testing revealed a rib cartilage injury, Gruden said via the team’s Twitter account.
The team’s Wednesday practice should provide a good idea of Kelley’s status for the Raiders game.
Kelley had 12 carries for 78 yards before leaving, with rookie Samaje Perine replacing him.
Reed has a chest sternum contusion. He played 40 of 71 plays, returning for the final drive after sitting out much of the second half.
