The Blues co-coach came off late after suffering a head knock in the 30-10 win over Kangaroos on Sunday, but has been given from doctor's approval to line up at Anzac Park on Sunday.

Tumut are looking to end their nine-year drought against the Tigers and it's a game Bristow didn't want to miss.

"It's a game I didn't not want to be a part of so I'm glad I've been given the all clear," Bristow said.

Co-coach Adam Pearce also returns to the side after missing last week with a shoulder problem.

With Pearce's return Ben Roddy is back in the centres, Michael Clark pushes out to the wing while Josh Webb will come off the bench.

The return of their leaders means the Blues are almost at full strength with Lachlan Bristow the only player still on the sidelines.

The crafty hooker hasn't played since lacerating his kidney when the teams met earlier in the season.

He needed surgery after the loss, but is still hoping to make an impact in the finals series.

Bristow has started light training and is hopeful of being cleared by the specialist next week.

Tumut's last win over Gundagai was at Anzac Park when they went on to win the 2010 premiership.

It was the last title in a golden period for the club and they've come through some dark eyes to get themselves back on top of the Group Nine ladder.

Tumut come into the clash with seven straight wins, including reversing their first round loss to Southcity six weeks ago.

Gundagai couldn't get the better of the Bulls last week and with plenty on the line Bristow is hoping they can deliver on the big stage to secure the minor premiership.

"It's never easy to beat them and everything is stacked up there is make it hard for us but if we want to be the best we have to beat the best," he said.

"There couldn't be any more incentive for what is on the line this weekend.

"A trip down to Gundagai with top spot on the line has all the makings of what we need to get up for it."

Gundagai scored a 16-6 win in front of a bumper crowd at Twickenham nine weeks ago.

However Tumut looked the better side for large periods of the clash.

The Blues struggled to make the most of their opportunities and that's the area Bristow wants to improve.

"They have very similar strengths to us so the most obvious thing is we need to control the ruck, win the ruck when we've got the footy and something we didn't do last time was take our opportunities when they come," he said.

"When you play the better side opportunities are few and far between so when we do get our chances we have to make sure we are taking the right options and capitalising."

One thing Bristow is confident Tumut have improved since their last clash with Gundagai is their attack.

They remain the best defensive team in the competition, but their ability to score points is one thing they've focused on in the build up to finals.

It gets put to the test on Sunday.

"It is something we've put a lot of work into," Bristow said.

"We were a pretty defensive based side for probably the first half of the competition, it was the way we wanted to go as we knew we had plenty of time to get our attack in order.

"It's something we've put a lot of work in over the last nine weeks, and the last four weeks in particular, and it is starting to pay off I feel.

"We still have some more improvement in us but it's definitely been a big improvement in our game."

The winner secures the minor premiership, the week off to start finals plus hosting rights for the major semi-final.

However a loss could see either side slip to third, and lose home ground advantage in the first week of finals depending on the result between Southcity and Brothers on Sunday.
