Reigning premiers Marrar are confident senior players Cal Gardner, Josh Hagar and Truman Carroll will be right for finals after missing this week's final round game against Barellan with minor complaints.
Unlike serious injury concerns Matt Parks (knee) and Damian O'Donoghue (hamstring), the experienced trio are expected back for the Bombers' next game, along with Jack Reynolds (unavailable).
"It's nothing too serious, but they're sore and they're obviously our older players and coming off a tough game, we're trying to manage them," Marrar coach Shane Lenon said.
"I'd be confident they'll all be right for next week."
Marrar's first final is likely to be Saturday's qualifying final against the winner of East Wagga-Kooringal and Temora (unless North Wagga are upset by the Northern Jets, and the Bombers beat the Two Blues).
Lenon said they're not taking the Barellan trip lightly, with Marrar's ins including 250-gamer Mitch Taylor, young gun Drew Beavan, tall Nick Cooper and key defender Adam Whyte coming in.
It will ensure valuable game time for Taylor and particularly Whyte who hasn't played since mid-June due to a quad injury.
"Whytey was close to playing last week but with the injury he had, we thought we'd give him the extra week," Lenon said.
"He's certainly a good in and a really good backman. It's really important for him just to get a bit of touch and confidence and to get through a game. It's not like he's had two or three weeks off so he definitely needs a game heading to finals."
The changes show Marrar's strength is in their depth.
"Our focus is definitely on Barellan this Saturday. We're not looking past that," Lenon said.
"You can't afford to take any side easy, and we'll back the blokes we've picked.
"We've been lucky with our under 17s winning the premiership last year. A lot of our team has come out of that and you call up young guys like Blake Walker and Archie Howard, it shows we're lucky to have that depth.
"And it's an opportunity for a few young blokes to put their hand up for selection in our first final."
