South Sydney coach Anthony Seibold said Rabbitohs and Queensland captain Greg Inglis showed he was back to his best with his stellar performance in a losing Maroons side on Wednesday night.
Fifteen months suffering an ACL injury, Inglis's long road back to the top was capped by an outstanding display in the 22-12 loss at the MCG.
"Greg was a great leader for Queensland last night," Seibold said on Thursday.
Seibold: We've prepared as if they're not playing
"I thought he was immense from a physical point of view. I really enjoyed watching him play and the physical presence that he brought.
"He's worked really hard to get himself into the condition he's in.
"I think the big thing for Greg is the confidence he would have taken out of playing like that on a bigger stage in rugby league."
Seibold said all four of his Origin players pulled up unscathed, in particular, Damien Cook who had concerns over a sternum injury and Dane Gagai who is on the mend from a fracture in his finger.

"There's no dramas with any injuries for any of the boys which is pleasing to hear," Seibold said.
"I spoke to Damien this morning he's fine, he pulled up a little bit sore obviously, I think he made over 50 tackles.
"I spoke to Gags literally five minutes ago, his finger pulled up really fine he said. I've spoken to the Queensland doctor and they're really comfortable with how they handled that injury and he's under no risk what so ever.
"They are going to fly directly to the Gold Coast so we will meet with them ... and get our medical staff to assess them and obviously make some decisions around whether they play or not later on this evening."
The Rabbitohs are geared up to celebrate Sam Burgess's 150-game milestone as they take on Titans on Friday night.
"It's an important milestone for him [Burgess]," Seibold said.
"He's been such an integral figure over the last six or seven seasons, whatever it is.
"He's really looking forward to it and the group's really looking forward to playing for him tomorrow night as well."
