The dynamic young Knights fullback is nursing an "annoying" cork above his knee but had a light run with the squad yesterday and says he is confident he will be right for the clash.

"I hate corks, they suck but they are just one of those things where you have got to look after it, ice it," he said. "It's definitely better than a broken bone but it's one of those annoying little things.

"I feel good now. I trained today and had my first run since the game and it feels pretty good. I should be right by the game. It's still a bit sore but I'm ticking all the boxes."

In a further boost for the Knights, key forwards David Klemmer and Tim Glasby are also both expected to play against Brisbane with Klemmer getting the all-clear following his wrist fracture and Glasby shrugging off the elbow ligament injury he picked up during Origin II.

"It has settled down really well," Glasby said. "It was quite stiff and sore after the game but it's come good over the last few days and structurally, it's pretty sound so they are happy for me to get out there as long as I'm comfortable."

Ponga dispelled any suggestion he may be suffering from a case of the 'blues' in the lead up to the Broncos clash following the Maroons' loss in Perth last Sunday and subsequent criticism of his own performance in just this third Origin appearance.

Asked how a young player such as himself handles a defeat like that, he said: "Pretty easy, that's last week. I've got to focus on the game this week. I just get around my mates, I love being around my mates and I just focus on the next thing at hand pretty much - that's what I do."

Glasby said the possible return of Klemmer to help combat a big Brisbane forward pack would be a huge boost for the home side.

"I'm not sure where Klem is at and where the coaches are at with him but he looks good to me so I guess it will be similar to me," he said.

"If he is comfortable and ready to go, they will let him go and if he does play, he is massive for us. He's been huge for us in the first half of the year and we certainly missed him against the Storm and the Rabbitohs.

"It would be great to get him back. The Broncos obviously have a big powerful forward pack so it's going to be a great challenge for us through the middle. When they get a roll on, they are very hard to stop."

Brisbane are coming off consecutive defeats to the Titans and Parramatta in their past two games and are viewing this game as potentially pivotal to their season.

They currently sit 12th, two wins behind the fifth-placed Knights, with a further loss likely to drop them even further down the peaking order.

Knights centre Jesse Ramien has no doubts the Broncos will turn up on Saturday desperately looking for an upset.

"I think a few teams are going to be coming for us after the bit of a streak we went on," he said. "But I think it's the same for us, we are treating it as a bit of a do-or-die. We want to be like that from here on until the end of the season."

Ramien said the Knights' 30 point loss to the Melbourne Storm in their last match may prove to be a positive in some respects.

"It sort of settled us down a bit," he said. "It showed us the areas we need to improve on. It showed us where our weaknesses were. To get that loss, it's good in a way to show us where we need to improve."

Ramien says he continues to search for his best form at the Knights and admits he hasn't played well enough to warrant State of Origin consideration this season.

"My attack is still not up to my best but hopefully that will come," he said. "I think I'm playing better as the season has gone on. Hopefully, it clicks a bit more the back end of the year."
