Waller (knee/back) remained sidelined for Thursday's practice, Tashan Reed of The Athletic reports.
Back-to-back absences don't bode well for Waller's chances of returning to action Sunday against Kansas City, with Friday's injury report destined to add clarity with regard to the tight end's Week 14 status. If Waller is out or limited this weekend, Foster Moreau will continue to see added opportunities in the Raiders offense.
