Eagles cornerback Nolan Carroll suffered a concussion in the second quarter of Sunday's game against the Atlanta Falcons. He is out for the game and was replaced by Leodis McKelvin, who is already nursing a hamstring injury.
Carroll's concussion further depletes a position that is already thin. Without Carroll, the Eagles have McKelvin and three rookies: Jalen Mills, C.J. Smith, and Aaron Grymes.
Carroll must enter the league-mandated concussion protocol and cannot play until he's cleared by an independent neurologist. The Eagles will face the Seattle Seahawks next week.
