The A&E drama stars Matt Passmore as a detective working in South Florida. He transferred from Chicago after being accused of sleeping with his captain's wife.
The series has performed well in the ratings for A&E and has now been handed another run.
The show, which also stars Kiele Sanchez and Carlos Gómez, is due to return for its third season in summer 2012.
It will be joined by the new season of Breakout Kings, which was renewed for a second run in July.
A&E also has a new drama beginning next year. Longmire, which stars Robert Taylor and Katee Sackhoff, focuses on a Philadelphia detective who moves to a small town in Wyoming.
