Miller (concussion) reverted to the Jaguars' practice squad Monday, per the NFL's official transaction log.
Miller made an impact on special teams, forcing a DeAndre Carter fumble on a third-quarter punt return. The loose ball was recovered by Chicago's Sherrick McManis, while Miller was flagged for a 15-yard unnecessary roughness penalty on the play. The fullback later exited the game with a concussion, and he remains in league protocol upon his return to the practice squad.
