The Canberra Raiders have been dealt an injury blow with prop Ryan Sutton ruled out with a calf injury on the eve of their crucial clash against St George Illawarra.
Emre Guler has replaced Sutton in the 17 to play at Wollongong on Sunday.
Sutton played every game since joining the Green Machine in the off-season and making his debut in the round-one win over the Gold Coast.
It will be Guler's fourth game of the season and seventh of his career.
The Raiders do have some good injury news with Nick Cotric expected to return from an ankle injury, to partner winger Jordan Rapana on the right edge.
The duo helped Dragons flyer Mikaele Ravalawa become an NRL player, but they're also the reason he left the Green Machine.
Ravalawa will run out for St George Illawarra at Wollongong on Sunday - the first time he'll play against his old club.
The 21-year-old winger made his NRL debut for the Dragons against North Queensland in round one, having spent a couple of seasons with the Raiders.
In that time he was the 2017 Canberra under-20s player of the year and also played for the Mounties in the NSW Cup.
He worked with Rapana and Cotric to develop his game - players he rates as two of the best wingers in the NRL.
If it wasn't for a potentially season-ending injury to Joey Leilua (neck), the Dragons right wing would be going head to head with Cotric.
But Cotric's switched to join Rapana on the Raiders right edge, with Canberra recruit Bailey Simonsson taking his place on the left wing.
While he was full of praise for Croker and Simonsson, they weren't the two he credited as his biggest mentors while with the Green Machine.
"Rapana and Cotric, they're dangerous wingers and they're pretty hard running and pretty skilful," Ravalawa told The Canberra Times.
"I will try my best to defend and attack myself. They're good players and they've been playing NRL for a couple of years now."
While they both helped him, they also stood in his way of making his NRL debut.
It's why he looked elsewhere and signed a two-year deal with the Dragons.
He's played 14 games in his debut season and is the Dragons' leading try scorer with nine - seventh overall in the NRL.
He also leads the Dragons for line breaks with nine.
His breakout season led to him making his international debut for Fiji, having been part of their 2017 World Cup squad.
Finding those opportunities was why he left Canberra.
"Yeah that was the main reason because they've got two [of the] best wingers in the comp, Jordan and [Nick]. They were pretty good," Ravalawa said.
"I'm pretty happy with my decision and coming and playing NRL now and making my debut it was great.
"They've pretty much got good backs there. They've got [Michael] Oldfield, Cotric, Simonsson, they've got some good edges there."
The Raiders hold a special place in his heart after recruitment boss Pete Mulholland spotted him playing rugby union in New Zealand, when he was at boarding school.
"I was in Christchurch in New Zealand. I went to play in Wellington and he saw me then and he recruited me then," Ravalawa said.
"I didn't even know. When I went back to Fiji. I had my agent back home and he was just talking to me about signing with Canberra. My journey just started there."
