Packers' Sam Shields won't return vs. Patriots with concussion

Green Bay Packers cornerback Sam Shields won't return to Sunday's game against the New England Patriots after suffering a concussion.

The Packers' cornerback was taken to the locker room for further evaluation. Expect Casey Hayward to take more snaps in his absence.
