Coach Wayne Bennett also confirmed lock Max Plath (calf) and forward Ray Stone (neck) were right to play as he made two significant changes to the team for Saturday night’s showdown at Suncorp Stadium.
Regular half Isaiya Katoa will come off the bench with centre Jake Averillo switching to the halves. Trai Fuller comes into the side at fullback with Hamiso Tabuai-Fidow shifting to centre.
Bennett said he had taken all of his own emotions about playing against the Broncos out of the equation.
The Dolphins have lost nine of their last 12 games to slip to 10th and need to win both remaining games to play finals, just like the Broncos.
“You can’t keep doing the same thing over and over again and expect a different result,” Bennett said.
“We have been sticking with that and been pretty loyal to that. I just thought we are at a place now where we have to give ourselves a chance.
“(Katoa) has been up for too long actually. He is only young and it does impact on them. Just little things in his game have fallen away.
“The pressure is not just in the game in the NRL. The pressure is at training. The pressure is in your lifestyle and everything around you. He is only in his second year and by the time he gets to 50 or 60 games he will be fine.
“He has been wonderful for us but it is a big game tomorrow and we wanted to make sure we had everyone playing who was confident about what they were doing.”
Averillo has played in the halves before at Canterbury and at youth level.
“It is a risk but I am in the risk business,” Bennett said.
