New England's Garoppolo suffers shoulder injury against Miami

Quarterback Jimmy Garoppolo was knocked out of New England's game against Miami on Sunday with a shoulder injury, meaning the highest-profile replacement in the NFL needed a replacement of his own.

Garoppolo — filling in for suspended quarterback Tom Brady — took a big hit from Miami's Kiko Alonso in the second quarter of the Patriots' game against the Dolphins on Sunday and left for further evaluation.

The Patriots did not disclose the severity of the injury, but said Garoppolo was ruled out for the rest of the game.

Garoppolo was 18 of 27 passing for 234 yards and three touchdowns in less than a half, as New England rolled to a 24-3 halftime lead. He was replaced by rookie Jacoby Brissett, a South Florida native who found himself facing essentially his hometown team in his pro debut. The Pats' emergency quarterback would figure to be wide receiver Julian Edelman.

There was a very scary scene in the first half of Sunday's early games as well.

Cornerback P.J. Williams of the New Orleans Saints needed to be placed on a backboard and taken off on a cart after he took multiple blows to the head while trying to make a tackle in his team's game against the New York Giants. Fox Sports reported that Williams was moving his extremities at a nearby hospital and was being evaluated for a concussion.
