Blake Austin is ready to seize the Wests Tigers' five-eighth position vacated by the injured Braith Anasta.

For some time now, we've been warned of a once-in-a-generation throng of promising talent bubbling away at Concord, a prodigious youth movement set to take the NRL by storm in a few years time. 

Well, that entire era has just been fast-tracked forward to this Friday night. 

With the careers of veterans Braith Anasta and Liam Fulton on a knife edge, the joint venture club will pin their finals push on a fullback, five-eighth and halfback boasting just 43 games between them. 

Compare that to the 496 games worth of NRL experience that'll be missing should Anasta and Fulton decide to hang up the boots this week, and you see just how monumental the task set before Blake Austin, Mitchell Moses and Luke Brooks will be. 

"They're kids, but we're playing the game we love," said lock Adam Blair on Tuesday. 

"This is what we're here for, to work hard for each other. They're going to have to step up now, and there's no better stage than the NRL to do what we do best."

Anasta is set to see a specialist on Wednesday to decide whether to play on with a partially torn bicep and should he decide to retire, Potter will turn to utility Austin to fill his experienced shoes. 

Responsible for more than half of those 43 games, it will be Austin's biggest opportunity of his four-year career to establish himself as a first grade starter. 

"I guess it's a time for me to stand up and possibly lead the team around leading into the finals, if Braith's not right. I guess you could say it's probably my biggest shot," he said. 

"I've finally get a good chance hopefully to get a crack. I feel like I've been playing some really good footy, but it's not enough yet. I've been coming off the bench and it's not where I want to be so I've got to step it up another level and hopefully try and cement down a spot. "

Having switched from Penrith to Concord over the summer, a matured Austin has proven to be a handy buy for the joint venture club after a string of positive cameos off the bench this year. 

"I think I'm slowly finding a bit more professionalism. I was probably a bit young and a bit naive to the fact that you had to work really hard to stay at the top in this game. So I put in probably the best off-season of my life and I'm just reaping a few of those rewards now," he said. 

"I guess it's not really my call to say whether I've earned [this shot]. But I will say that I've been happy with my footy. And I feel like I'm ready to have another crack at the starting team and hopefully move my way into being an 80-minute footballer." 

Moses made a solid debut at fullback in their 26-10 loss to Penrith last week but, having grown up alongside his high school halves partner in Brooks, is being groomed as the club's long-term pivot. 

Austin said it was up to him to prove he belongs there first. 

"Mitch is a good young kid. It's undeniable – he's going to be a freak of the game. Obviously he's a local junior, so it's good for the club that he got a debut on the weekend," he said. 

"It comes down to me. If I want to play good enough then I'm sure Mick's going to put me in there and if not, he's going to look for other answers. It comes down to me."

Fulton is expected to decide on his future when he returns from a week in Fiji considering retirement after a series of concussions.
