Washington Redskins running back Rob Kelley is not expected to play Sunday in a prime-time game against the Oakland Raiders due to a rib injury, a source told ESPN's Adam Schefter.
The 24-year-old was listed as questionable. His absence should mean expanded roles for rookie Samaje Perine and Chris Thompson.
Kelley was expected to be supplanted by Perine this offseason, but held onto the starting job through training camp, and has 108 yards on 22 carries this campaign.
