Some key actors might not play in the big Halloween show Saturday at Autzen Stadium.
For USC: Both running back Joe McKnight and tight end Anthony McCoy suffered injuries against Oregon State. McKnight suffered a severe cut on his hand, while McCoy sprained his ankle. McKnight played with his injury, but McCoy had to be helped off the field. Coach Pete Carroll told reporters on Sunday that McCoy's injury is not the dreaded "high ankle" sprain, which can take weeks to recover from.
For Oregon: The Ducks' defense might take a couple more hits. Cornerback Talmadge Jackson hurt his back against Washington, while linebacker Josh Kaddu suffered a "foot/ankle" injury in the third quarter. On offense, guard Mark Asper conducted postgame interviews with his left foot in a boot.
Of the group, McCoy and Kaddu might be the most questionable to play Saturday, but obviously there will be more reports throughout the week.
