Waller (knee/back), who has missed the Raiders' past four games, is expected to be placed on the reserve/COVID-19 list Wednesday, Paul Gutierrez of ESPN.com reports.
Raiders interim head coach Rich Bisaccia had previously been hopeful that Waller might practice Wednesday, but the tight end's impending move to the COVID-19 list will thwart those plans. Even if he's able to test out of the NFL's COVID-19 protocol in expedient fashion, he'll more than likely miss multiple practices this week, which could make it difficult for him to gain clearance for Sunday's game against the Colts.
