Waller (knee) is listed as a limited participant on Wednesday's practice report, with the Raiders holding a walk-through session for the second straight day as they prepare for Saturday's wild-card game in Cincinnati.
Waller returned from a five-game absence for the Raiders' overtime win over the Chargers in Week 18, catching two of nine targets for 22 yards in the 35-32 victory. He wasn't at his best in his first game back, but he played close to his normal allotment of snaps (78 percent). Though he and the Raiders will face a quicker turnaround than usual for Saturday's postseason opener, Waller had a big game earlier this season against the Bengals back in Week 11, when he produced a 7-116-0 receiving line in a 31-13 loss.
