Cowboys aim to improve defense against Dolphins after last week's loss, with Cotter, Farnworth, and Nikorima returning to play.
North Queensland hope a return home will provide the foundation for a return to form when they host the high-flying Dolphins on Saturday evening.
The Cowboys suffered a disappointing loss to the Raiders in Canberra last Sunday and coach Todd Payten will be eager to see an improvement in their defensive resolve.
That area of the game will take on an even greater focus against a Dolphins side that has piled on the points in recent weeks.
