Following the decision, Cousins told reporters: "I need to be ready to go, continue preparing as I have. There was nothing dramatic with the decision, I was just told by the coaches that they'd be going with me this week.
"I'm just going to try and help this team win; as starter, backup, whatever. It's tough circumstances being 3-10 but I've just got to be ready to lead the team.
"Robert never backs down and that's a quality I admire from him. He never flinches and he'd like to be out there. I hope that I can take what I've learnt from him and help the team."
Cousins has featured in just two matches so far this term.
