The South Sydney Rabbitohs are reportedly ramping up talks to secure the long-term future of Lachlan Ilias despite Thursday night's horror show which saw him hooked against the St George Illawarra Dragons.
Cook has been on a long-term deal, while Walker, 32, signed a one-year extension to remain with the club for 2023 on November 1 last year - the first day he could have received offers for the 2023 season from rival clubs - effectively snubbing former South Sydney coach Wayne Bennett and the Dolphins in the process.
Despite that, the club are now unsure about both he and Cook, with South Sydney's form taking a major hit this year.
Cook in particular has stiff competition in the dummy half role, with Peter Mamouzelos - who played junior football alongside Lachlan Ilias and Blake Taaffe for the club, snapping at the under pressure NSW Blues' Origin hooker's heels.
News Corp's Brent Read told Triple M that Mamouzeols needs game time, but that the Rabbitohs still want Cook contracted beyond the end of 2023.
“What makes it really interesting is they’ve got a young kid Peter Mamouzelos who has got huge raps on him at hooker,” Read said.
“Souths want to keep him [Cook] so they will start those negotiations next week but it will be interesting to see how it plays out,” Read added.
“Obviously with Souths you saw what happened with Adam Reynolds. They didn’t want to block Lachlan Ilias’ path and Cook is sort of in a similar position. It’ll be intriguing to see how that one plays out.”
Meanwhile, News Corp are reporting that the Rabbitohs are still hellbent on securing Adam Reynolds' long-term replacement Ilias to a longer deal.
It's understood the club have tabled a deal which would keep him at Redfern until at least the end of 2025, with CEO Blake Solly saying they were hopeful he would elect to stay.
“We are hoping Lachie commits to the club long-term,” Solly said.
“We see him as a huge part of our future and he has bright future with the club. He came through our Jersey Flegg and NSW Cup system.
“Lachie is well liked by everyone at the club and we have made it clear we want him to have a long-term future here.”
