Raiders coach Dennis Allen's day-after-an-exhibition conference call took on the tone of a medical update presser early Saturday evening.The highlights, or lowlights, less than 24 hours after the Raiders' 31-27 defeat in Arizona: Receiverreturner Jacoby Ford's sprained foot may keep him out of action into the regular season and yes, it is the same foot, his left one, he sprained last season that kept him out of the lineup for most of the second half of the season."If you ask me, is there a chance (he could miss regular-season time), yeah, there's a chance," Allen said. "But we've still got to continue to look at it to see what type of time frame we're looking at." Backup quarterback Matt Leinart (cut right index finger) and running back Mike Goodson (shoulder weakness) are going to be O.K., Allen said. Receiver Darrius Heyward-Bey, who injured a shoulder against the Cardinals, was not considered to have a "serious" injury but will be monitored this week in practice. Allen "is hoping" to have both tight end Brandon Myers (shoulder) and running back Taiwan Jones (hamstring) back in practice this week. Receiver Denarius Moore (hamstring) is also getting "closer," per Allen, but there is no timetable on his return either. Linebacker Aaron Curry (knees) has returned from a week-plus in Los Angeles getting treatment and worked out with a running program for the Raiders coaches Saturday and "looked pretty good so we'll look at him (Sunday) and see where he's at," Allen said, "kind of evaluate him as we go along."The spate of injuries at the skill positions raise the specter of the Raiders looking outside the box, especially with such veterans still unemployed as receivers Plaxico Burress and Chad Johnson and running back Ryan Grant.And as such, Allen was asked if the Raiders needed to look at potentially adding some players now."We're going to look at that," he said, "as far as if we need to add somebody or not."Especially at returner, what with the injured Ford returning both kickoffs and punts."Right now we're looking at Bryan McCann," Allen said. "But that's obviously a position we've got some concern over. We're going to be evaluating the guys we have here but we're also going to be looking at the rosters of the other 31 teams and see if there's somebody that comes available that can help us in that regard."
