Cody Walker has been declared fit to play in South Sydney's historic season-opening clash against Manly in Las Vegas.
Souths coach Jason Demetriou confirmed on Friday the playmaker had overcome the calf injury that ruled him out of the All Stars match last month.
"He's a world-class player. Really happy that he was able to get the training done in San Diego," Demetriou said.
"That was important for his prep, to be able to have a full week of training going into round one.
"It's got him in a good headspace and the team will benefit from that for sure."
