Nick Foles will start in his place and Tyler Bray will serve as the backup.

Smith said Wednesday he never failed any of the concussion tests administered after each of the blows, the second of which knocked him from the game. But after consulting with coach Andy Reid and others in the front office, it was decided he would not be active this week.

Smith will run the practice squad and hopes to play next week at Carolina.

Foles was sharp in relief against Indianapolis, going 16 of 22 for 223 yards with two touchdowns and no picks in the Chiefs’ 30-14 victory.
