Raiders coach Antonio Pierce announced the decision Wednesday morning as the team began preparations for the Dolphins at their Henderson headquarters.

Ridder replaced Minshew in the Raiders' most recent game. He completed 11 of 16 passes for 74 yards and a touchdown in Las Vegas' 41-24 loss at Cincinnati on Nov. 3. The Raiders signed Ridder off Arizona's practice squad on Oct. 21 with Aidan O'Connell going on injured reserve with a broken thumb.

The Raiders are sticking with Gardner Minshew as their starting quarterback for Sunday's game against the Dolphins, coach Antonio Pierce said Wednesday.
