Miami Dolphins have opened up a seven-point lead over the Cincinnati Bengals after two quarters at the Sun Life Stadium.
The first passed without any score, but Mike Nugent's 31-yard field goal early in the second put the Bengals in front.
However, the Dolphins fought back as Ryan Tannehill pushed over the line from a yard and Caleb Sturgis kicked the extra point.
Sturgis then extended the lead to 10-3 before half time with a field goal from 36 yards.
