McFadden continues to make progress from the mid-foot sprain that has kept him out of the Raiders' last two games but has yet to resume full workouts. Ford is wearing a protective walking boot after injuring his foot in last Thursday's win over San Diego.
Neither player even attended Oakland's first practice since a two-day break, and coach Hue Jackson declined to say what the chances were for McFadden or Ford being available for Sunday's game at Minnesota.
"We have a team of doctors that handle that," Jackson said. "They're normally going to tell me when a guy can play and I trust their judgment and what they do. Nobody's been ruled out as of now, so we'll go through the week and see where we're at."
Bush ran for a season-high 157 yards and a touchdown and had another 85 yards in receptions. The 242 yards from scrimmage were the most by a Raiders player since Bo Jackson had 235 against Seattle on Nov. 30, 1987, and the fourth-most in franchise history.
Moore nearly outdid him.
The rookie receiver from Tennessee caught seven passes for 143 yards and two touchdowns and repeatedly gouged San Diego's secondary for big gains. Included in Moore's night was a remarkable 46-yarder that he caught with his fingertips wrapped around the point on the ball after the pass from quarterback Carson Palmer sailed over Moore's head.
That win, coupled with Denver beating Kansas City on Sunday, gave Oakland sole possession of first place in the AFC West. It's the first time since 2002 that the Raiders have had the outright division lead this late in the season.
Jackson has had to juggle his lineup most of the year due to players being hurt.
In addition to McFadden and Ford, quarterback Jason Campbell, center Samson Satele, fullback Marcel Reece, tight end Kevin Boss and reserve wide receiver Louis Murphy have all missed playing time as a result of injuries.
McFadden has not practiced since getting hurt against Kansas City on Oct. 23. He limped through the locker room with the aid of crutches and his right foot in a boot the following day and has made slow progress since.
"I know we're getting closer to getting him back out here," Jackson said. "I know he's working his tail off. When I saw him this morning he looked good. Until we get closer later on in the week and we know exactly where he is, I don't want to speculate."
Ford, who doubles as Oakland's kick returner, went down with a similar foot injury against San Diego on Thursday. He was scheduled to undergo an MRI over the weekend but the results were not yet available.
Moore, who filled in on offense when Ford got hurt, will also replace him on special teams if the second-year wide receiver is unable to play against Minnesota.
"We're going to know more as we move through the week," Jackson said. "By (Tuesday) when we really start laying all the foundation for a game plan, I have to know who has a possibility of playing, at least."
Even without two of its best offensive players, Oakland still had little problem moving the ball and scoring against San Diego, thanks to big nights from Bush and Moore.
It was the type of night that would have made late Raiders owner Al Davis proud, seeing two of his lower-round draft picks flourish despite playing in backup roles most of the season.
"We have a whole bunch of talent on the offense and defense, where if one goes down we have another to step in and take his place," Moore said Monday. "We all have faith in our teammates."
