Paxton Lynch's dismal outing in Oakland took a turn for the worse in the second half of Sunday's game.

The second-year Denver Broncos quarterback was ruled out against the Raiders after suffering an ankle injury. Lynch pulled up following a rollout pass to Emmanuel Sanders in the third quarter and was helped off of the field.

Trevor Siemian -- previously benched for Brock Osweiler, who was benched for Lynch this week -- will play in Lynch's absence.
