The Las Vegas Raiders have placed Darren Waller and Hunter Renfrow on injured reserve. 

Waller has been battling a strained left hamstring since a Week 5 loss to the Chiefs and already has missed Las Vegas' last three games.

Both Waller (three years, $51 million) and Renfrow (two years, $32 million) signed offseason extensions, but neither has been able to stay on the field this year.
