For Knights prop Korbin Sims this Monday’s match against North Queensland will take on extra meaning.
It will be the first time he’ll line-up against his two older brothers Ashton and Tariq at any level.
The trio played alongside each other at last year's World Cup for Fiji, while Korbin also joined forces with Tariq when the pair played under 20s at the Brisbane Broncos back in 2010.
Korbin faced Ashton in his NRL debut versus North Queensland in round three last year, but the three siblings have never competed against each other.
This is set to change on Monday night when Korbin's Knights take on Ashton and Tariq's Cowboys at 1300SMILES Stadium in Townsville.
And while the Sims lads are extremely close, brotherly love will count for little once they cross the white stripe on Monday.
"No there is going to be no laughing, trust me," Sims tells Knights TV.
"As soon as we step on the field we are not going to know each other.
"So I’m expecting a good hard match and so will they.
"They are strong, aggressive dudes and that’s just the way we were raised and it’s just the way that we play our football.
"So I’m looking forward to it."
As the youngest sibling of the Sims clan at 22, Korbin can't wait to take on his two older brothers Tariq (24) and Ashton (29).
He says the match-up against his brothers evokes memories of their backyard battles growing up in Gerringong on the NSW South Coast.
“Yeah sort of, except it used to be Tariq and I versus Ashton when we were younger," he grins.
“It’s going to be really good and a good test for me, especially just coming back into first grade.
“It’s going to be a good day for us.
“We’ll be looking back-to-back wins, but obviously playing against both my brothers at the same time is going to be really fun.
“I played against Ashton last year in round three in my debut and Tariq didn’t play.
“So I’m tipping that both of them together, they are going to have a bit of fun."
Sims is also looking forward to performing in front of family and friends.
“They always support us," he says.
"I’m not sure if mum is going to be up there yet, but dad is going to be watching on TV no doubt and my two sisters will be watching as well.
“So we’ve got a lot of love and support for us anywhere that we play, so it’s nice to know that."
Sims performed strongly in his first NRL game for 2014 against Cronulla on Sunday, coming off the bench and making 128 metres in 38 minutes of football.
While he was happy with that performance, he knows he must continue that type of form against North Queensland's representative bookends Matt Scott and James Tamou.
“Well I have to, because if I’m not bringing a good performance I’m not going to be playing in the side," he says frankly.
“So I’m just looking to not only repeat what I did last week, but hopefully better it.
"They (Cowboys) have got to two Australian props up there, which is always going to be hard to get over the top of.
"But in saying that we did a good go of it last year and I reckon this year we are coming into a bit of form, so I reckon we’ll go close to getting over the top of them again.”
