The Knockouts For the Knockouts, Nate Ruess was assigned as a mentor for contestants in all four teams. After announcing Anthony Riley's withdrawal from the competition, Pharrell grouped three of his team members into one knockout, in which two contestants from the trio advanced and one being declared loser. Just like season five, the coaches can steal one losing artist. The top 20 contestants will then move on to the "Live Shows".
