Waller (shoulder) was limited at practice Thursday, Rachel Gossen of the Raiders' official site reports.
Per Tashan Reed of The Athletic, Waller sported a red non-contact jersey Wednesday, but by Thursday the tight end was able to practice without said jersey. Waller now has two more chances to upgrade to full practice participation ahead of Monday night's game against Kansas City, which he'll presumably need to do in order to avoid a Week 5 injury designation.
