Any defensive back who has to go up against Detroit Lions receiver Calvin Johnson better step up his game. Miami Dolphins cornerback Brent Grimes got his chance to cover Megatron on Sunday, and he was ready for the challenge.

In the second quarter, Lions quarterback Matthew Stafford tried to connect with Johnson on a long pass to the end zone. However, Grimes made an incredible play to deny Johnson his second touchdown of the game.

Grimes' interception helped prevent Detroit from building on its 10-0 lead.
