Waller (knee/back) isn't practicing Wednesday, Paul Gutierrez of ESPN.com reports.
Raiders interim head coach Rich Bisaccia referred to Waller as day-to-day on Monday, perhaps sparking hope for the tight end to return to practice Wednesday. It won't play out that way, giving Waller two more chances to get on the field before Sunday's game in Kansas City. Fill-in tight end Foster Moreau played 89 and 85 percent of snaps for the Raiders the past two weeks, catching two of eight targets for 37 yards between those contets.
