High ankle sprains could keep running backs Darren McFadden and Mike Goodson on the bench for Sunday's game at the Ravens.
Neither practiced for the Oakland Raiders on Wednesday or Thursday, but coach Dennis Allen wasn't ready to declare them out for Sunday's game.
"The great thing for me is that I don't have to make that decision right now,"Allen said. "I am going to let the week play out and see where they are at the end of the week. We are taking off Friday afternoon, so I'll know by then whether they're going to be able to play or not."
Also, defensive tackle Richard Seymour (knee/hamstring) and cornerback Shawntae Spencer (foot) didn't practice for the second day in a row.
Oakland had trouble running the ball before they went down. McFadden has 455 yards rushing on 139 carries, just an average of 3.2 per carry, and only two touchdowns.
In 2011, McFadden rushed for 614 yards on just 113 carries, a 5.4 average, in seven games because of a foot injury.
Not having to game plan for him should be a relief, but not the way Ravens coach John Harbaugh sees it.
"It's a little bit unpredictable. We'll probably see as the week goes along, but we're really not worried about it," Harbaugh said. "You just can't be. They are going to run their offense and whoever they put there at running back is going to run the same plays they are running."
The Ravens have had trouble stopping the run. They allowed the Cleveland Browns to rush for 116 in last week's 25-15 win, a massive improvement over their previous three games in which they allowed an average of 207 yards pe game.
Still, after being the NFL's second-ranked defense against the run a season ago at 92.5, the Ravens have plummeted to 28th by allowing 139.5 per game. That's the worst ranking of any team with a winning record.
"They're not going to change their whole offense. The may, obviously, lean in some direction based on which back is back there. Maybe they will sign somebody, but we'll try to defend the offense."
