As expected, the Lions will be without their top safety Sunday against the Raiders.
Tracy Walker, who suffered a knee injury against the Giants and was held out of practice this week, has been ruled out. His status, according to Matt Patricia, remains "day to day."
Detroit might be without its top cornerback, too. Darius Slay is questionable with the hamstring injury that kept him out of the Giants game. Slay did take part in a full practice on Friday, a good sign for his availability on Sunday.
A surprise addition to the practice report on Friday was A'Shawn Robinson, who showed up with an ankle injury. Robinson is questionable as well.
Same goes for guard Graham Glasgow (back), running back Tra Carson (hamstring) and Damon Harrison (groin). Harrison re-injured his groin against the Giants and was briefly removed from the game, but said afterward he felt fine. He should be good to go against the Raiders.
On the other hand, Mike Daniels is likely to miss his fifth game in a row with a foot injury. He practiced in limited fashion this week and is doubtul for Sunday.
The Lions head to Oakland looking for their second win in a row.
