When the players were back on their feet Gorillas ran riot over the visitors in a 64-0 rout, adding to a rough day for CSU after their forced second grade forfeit earlier in the day.

Narromine pummelled CSU through the middle of the park with a strong, no nonsense brand of rugby for which the university side had no answer for.

CSU coaching staff member Peter Plunkett said the team did what they could with a heavily depleted side.

"They were a very strong outfit and we just fell to their physicality at the breakdown. They're a very well drilled side getting ready for finals football and we've got a makeshift side," he said.

"Credit goes to Narromine. They played a forward-oriented game and their backs also ran straight and hard. They don't make many mistakes. They play to their strengths and don't play with too much flair.

"They don't chance their arm a lot but against a smaller side like us, especially in the backs, they're always on the front foot. We didn't help our own cause either with a lot of penalties."

Nine different Gorillas players got themselves on the try scorers sheet in the one-sided clash.

Plunkett said there will glimpses of promise from CSU but the Narromine defence was a different sort of beast.

"We tried different things and they maintained their structure but they just couldn't maintain possession against the bigger and stronger side," he said.

"Towards the end our blokes were still running back to halfway ready to go again. They hadn't thrown the towel in.

"Narromine were empathetic to our situation. Both Narromine and Mudgee have now given us players in second grade, for what was effectively a trial game. Half of our first grade side was probably coming from that second grade team.

"They also allowed us to play uncontested scrums and let us keep our full compliment."
