Sydney Roosters coach Trent Robinson has revealed that things were off in Boyd Cordner’s comeback over a month ago as the club great attempted to fight his way back from numerous head knocks and concussions.

Speaking to The Sydney Morning Herald, Robinson said Cordner was struggling post-training.

“He hadn’t even started contact,” Robinson said.

“Five weeks ago, we knew things weren’t right. He wasn’t close to playing.

“He’s much better than he was, but he’d had enough advice from his doctors that if symptoms persist, he couldn’t return. And they just didn’t subside like they should have. Post-training, you’re supposed to have a buzz. He was feeling the opposite.”
