Bills' Zack Moss: Concussion confirmed

Bills head coach Sean McDermott confirmed that Moss was placed in the concussion protocol following his early exit in Sunday's 9-6 loss to the Jaguars, Alaina Getzenberg of ESPN.com reports.

Before leaving, Moss carried three times for six yards and reeled in two of his four targets for 18 yards. Moss now will have to clear the five-step protocol to make himself available for the Bills' Week 10 game against the Jets, but if the second-year player doesn't get the green light to play, Devin Singletary could be in store for a three-down role out of the Buffalo backfield.
