London - New Orleans Saints cornerback Ken Crawley made the play of a tight first half Sunday at Wembley Stadium when he intercepted Miami Dolphins quarterback Jay Cutler in the end zone. The Saints ended the half with a 3-0 lead as Wil Lutz made a 43-yarder as time expired.

The Dolphins had marched down the field on their opening possession and looked poised to score before Crawley intercepted the pass intended for tight end Julius Thomas.

It was a fairly sloppy half of football as both teams were hit were numerous penalties and the coach-to-player communication system was down early on as well.

The Saints' other best scoring chance ended with a missed 41-yard field-goal attempt by Lutz.

Safety Rafael Bush and linebacker A.J. Klein sacked Cutler in the first half with both plays forcing Miami punts. The Saints lost linebacker Alex Anzalone and tight end Josh Hill to injuries in the half.
