Brothers' premiership aspirations, and their bid to stay in fifth place, face their toughest test with a trip to Anzac Park on Sunday.
The Wagga side has been white hot in the last month, with four straight wins moving them into a finals position, but now have to tackle competition leaders Gundagai as they look to cement a place in the finals.
Brothers are currently a win, plus percentage, in front of Temora but with a clash against the Dragons to come halfback Cameron Breust knows it's another big game for their mid-season revival.
"It's huge as we've got Temora hot on our tail and need to cement our top five spot," Breust said.
"They're a top two team so it's obviously a big clash for us."
Brothers were winless in their first five games, including a 38-20 loss to Gundagai when the teams met at Equex Centre earlier this year.
However they've only lost once since.
An improved defensive effort has been attributed to the turnaround and with Gundagai having the second best attacking record in the competition Brothers expect it will be put to the test.
They've conceded an average of 10 points per game in the last month and Breust believes it's the key to picking up the result.
"We've just got to keep playing with the attitude we have in defence at the moment," Breust said.
"It speaks for itself with not many points scored the last few weeks.
"Gundagai probably have the best forward pack in the comp so have to meet them in the middle."
Two of their past four wins have been over finals bound Tumut and Albury, but the clash at Anzac Park shapes as their biggest test since being thrashed by 40 points against Southcity five weeks ago.
It's been a big turnaround and now the Brethren have to handle a lot more expectations up against a Tigers outfit who have dropped two of their last four games.
Breust believes they are up for the challenge.
"We're struggling with a few injuries at the moment so to be playing the footy we are is unbelievable," he said.
"The boys are just putting in together and working so hard."
Brothers have made a few changes to the side after the 36-4 win over Kangaroos.
Jordan Little comes out of the side after struggling with an ankle problem with Jackson Newling, who came off the bench for his first game in two months after a knee injury, replacing him in the centres.
Ben Schreiber returns to the team in the second row with Liam Carey shifting to lock, enabling Aaron Wynne to return to his regular role at hooker with Breust back at halfback.
