Isaac Liu will likely join Victor Radley and Sam Verrills in the Sydney Roosters casualty ward as they count the costs of one of their gutsiest wins in years.

Known for their skills, talent and experience, it was the Roosters’ hunger and toughness that shone through in Friday night’s 26-12 win over St George Illawarra.

Already without James Tedesco (concussion), Josh Morris (calf) and Nat Butcher (ribs), the Roosters went down to 15 men after 22 minutes with Radley and Verrills foreced off the field before halftime.

The pair will both go for scans, but the early diagnosis is that they have almost certainly suffered season-ending anterior cruciate ligament tears.

Liu then battled on a broken rib that will likely see him sidelined, while Boyd Cordner shrugged off an early groin injury.

Robinson also revealed winger Brett Morris couldn’t sit down in meetings all week due to back complaints before he scored a hat-trick in the win.

“It was really incredible some of the performances out there,” Robinson said.

“Really proud of them.

“It’s easy to talk up the Roosters at the moment.

“But it’s not that for that reason. I’ve said it before I really like walking in to coach these guys every single day. They’re just outstanding.

“It was just little things here and there, they just kept adapting and moving. They got stronger defensively as the game went.”

In response, the Roosters’ middle stood up.

Sio Siua Taukeiaho played unchanged for 80 minutes, while Jared Waerea-Hargreaves was out there for all but eight of them.

“They just said: ‘We’ve got this’,” Robinson said.

“We went out there and (trainer) Travis Touma got told to go away, politely.

“They actually sent a message back to me, and said we’ve got this half.

Joey Manu was also good at fullback, setting up one of the tries of the year as bombed, chased through, leapt to regather and flicked the ball back to Waerea-Hargreaves to score.

Joey played twice fullback last year. I feel like his backfield carries have really improved at centre this year,” Robinson said.

“And I think we saw that at fullback.

“His carries were really good. His creativity that Joey has on both sides of the field was needed.”

The Roosters should at least have all of Tedesco, Josh Morris and Butcher back for next week’s heavyweight clash with Melbourne on Thursday night.
