With centre Brayden Draber sidelined with a rib cartilage complaint Tom Hickson will move into the centres while Malik Aitken will start at hooker.

Jesse Bellchambers is also unavailable for Sunday games, and with halfback Jordan Anderson still out suspended, the Blues have called on their Weissel Cup hooker to come into the number nine jersey.

Aitken came off the bench in the 30-12 win over Gundagai last week and co-coach Zac Masters is confident he's up to the bigger role.

"He'll be great for us," Masters said.

"He did a good job when he came on for us at the end of the game last week and it's another reward for the hard work he's put in over the pre-season.

"He's been one of our best trainers so it is a good reward for him and his progress."

Tumut are looking to back up their win over Gundagai.

It is something the club has struggled with in the past, including coming unstuck against Kangaroos in the same scenario two seasons ago.

However Masters is confident the team is better prepared now.

"It is always a tough task backing up after a tough game like it always is against Gundagai but I'm pretty confident in the side, especially being a young side," he said.

"We've got a lot of youth in our side which helps with that back up."

Kangaroos started their season with a 34-16 win over Brothers last week.

Masters believes they will be one of the improvers from last year.

"It will be a good challenge as Roos are going off a good win, they have recruited well and have a very strong side," he said.

"By all reports they are fit and fast so they are going to be a tough challenge for us but if we bring the same effort that we did last week then we will be right."
