Wests Tigers prop Keith Galloway is out of the running for NSW's team for Origin I with a dislocated knee cap injury expected to keep him off the field for two to three weeks.

Galloway had been among a long list of front-rowers fighting for a spot on the Blues bench.

His injury opens the door for in-form Dragon pair Michael Weyman and Justin Poore to both cap remarkable rises to Origin football with NSW selectors eyeing two props to support Test duo Luke Bailey and Brent Kite.

Elsewhere Penrith centre Michael Jennings will have to continue to struggle with a throat infection as the preferred method of treatment for the illness involves the use of a substance recently added to the WADA list of banned substances.

Jennings is suffering from an inflamed airway but the medicine club doctors would usually prescribe was put onto the banned substances list following the 2008 Beijing Olympics.

"Just prior to the Olympics a lot of athletes were using it to counter-act the effects of the bad air in Beijing," said a club spokesman.

"WADA put it on the banned list after that and we cannot use it today."

Backrower Trent Waterhouse is the biggest concern for the Panthers ahead of Saturday's home game against the Sydney Roosters as he is suffering from a hyphema in his right eye.

Waterhouse, a bolter for the NSW Origin side, was poked in the eye in the win over Cronulla and rushed to Westmead Hospital after the game with officials concerned at the bleeding in his eye.

"He has been told to rest up and not do anything and he should be right again for the game this week," said a club spokesman.

"He will come back to us later in the week and we will assess him."

But in good news for the Panthers, backrower Frank Pritchard was back running at training on Monday, easing concerns over a soft tissue injury in his right foot.

"We were not expecting him to be running today but he has just pulled up really well," said club physio Tony Larven.

And utility Luke Lewis is expected to overcome the severe shoulder cramps he suffered against Cronulla to play on Saturday.

The news wasn't good at Parramatta with halfback Kris Keating confirmed to have a broken jaw and ruled out for up to three months while prop Weller Hauraki is out for four to six weeks with an ankle injury.

Keating suffered the fracture in a head clash with Manly's Anthony Watmough and is expected to miss eight to 12 weeks.

Former Sea Eagle Jeff Robson is expected to fill the halfback vacancy against South Sydney on Friday, although under 20s star Daniel Mortimer could be called in for his NRL debut.

The Rabbitohs meanwhile are not concerned about halfback Chris Sandow's ankle injury, but still sent him for precautionary x-rays on Monday.

The Sydney Roosters will be without Craig Fitzgibbon (up to two weeks) with an ankle injury and Sia Soliola (up to six weeks) with a medial ligament injury for the trip to Penrith.

Complicating matters for under siege coach Brad Fittler, young forward Martin Kennedy suffered an ankle syndesmosis injury in the under 20s game last Saturday and will be out for an extended period.
