Dolphins' Kendall Fuller: In concussion protocol

Fuller is in the concussion protocol after exiting Miami's 24-3 loss to Seattle on Sunday, Marcel Louis-Jacques of ESPN.com reports.

The starting cornerback allowed a 71-yard touchdown to DK Metcalf and finished with three tackles (two solo) and a pass defensed. Fuller's status in the concussion protocol leaves his availability for Week 4 in doubt. His replacement Sunday, Storm Duck, also left the game with an injury.
