Running back Jamaal Charles, along with tight end Anthony Fasano, cornerback Phillip Gaines and linebacker Tamba Hali, practiced Friday in the Chiefs' last day of preparation for the Oakland Raiders.
Charles and Fasano, who are both dealing with knee issues, are officially listed as probable, Hali, who also has a knee issue, is questionable and Gaines is listed as doubtful as he deals with a concussion.
Reid confirmed that he would have full use of Charles on Sunday after practice on Friday.
Defensive end Allen Bailey was the only Chiefs player to miss practice all week as he, like Gaines, continues to deal with concussion symptoms.
Bailey is officially listed as out for the game against the Raiders, so expect Vance Walker to once again step into the lineup in his absence.
Last week, Walker played in a season-high 42 snaps against the Cardinals, the most since playing in 23 against the St. Louis Rams in Week 8.
Walker spoke about being a primary piece of the defensive line rotation last week, a role he will play once again this Sunday against the Raiders.
"It felt pretty good," Walker said. "It's something I hadn't done for a while but it felt pretty good, pretty natural, so I'm happy to get out there and help the team."
With this being the second time the Chiefs will see the Raiders, his former team, Walker also said that there are certain things the Chiefs can do better from the first time around.
"Just a lot of little things," he said. "Tackling, gap assignments, a lot of times we were trying to do too much, [like] trying to make plays and just being smarter as a defense."

As far as the secondary goes, with Gaines likely inactive, Reid said that it would be a mix of players he described as "the whole crew" that would replace him, including Marcus Cooper, Jamell Fleming and Chris Owens.
The Chiefs practiced Friday in their third day of preparation for the Raiders with nearly a full team, but that doesn't necessarily mean they will all be active come Sunday afternoon.
- Gaines, Fasano and Hali were all limited today for the Chiefs.
