Wests Tigers halfback Luke Brooks will have scans after taking a knock to the thumb in his side's loss to Newcastle, while representative stars Aaron Woods and captain Robbie Farah are also in doubt for next weekend's clash with Cronulla.
The Tigers have three rounds of the NRL season remaining to salvage some pride with their 24-18 loss to the Knights on Saturday leaving them in a battle to avoid the wooden spoon.
Woods suffered a knee injury which forced him off the ground inside the opening 15 minutes after he collided with a teammate, bumping the outside of his knee when attempting a try-saving tackle on Akuila Uate.
It was initially feared Woods had done season-ending medial ligament damage but it was revealed the prop had re-aggravated scar tissue.
"He could possibly be OK for next week but that will be the next few days we'll see that," said coach Jason Taylor.
"He's had that injury a few times and it was a recurrence of a similar injury where his knee opened up a little bit, so the guys were concerned that it was worse than it seems it might be now."
Tigers physio Peter Moussa told the club's website Farah has a cheekbone problem would be further assessed on Sunday.
"He's pretty sore. We'll just have to look at it in the medical and make a decision on whether he gets scans," he said.
Dynamic halfback Brooks played out the match in pain as the Knights stormed home after a slow start.
"Brooksy took a knock to the thumb and was complaining in the second half but he got through the game. At the moment, it's pretty sore and swollen and we'll look at it in the medical as well."
"He's already got an X-Ray referral, so we'll get that sorted."
There was some good news for the Tigers with Chris Lawrence expected to return from an ankle injury while Martin Taupau is back from suspension for next Saturday afternoon's clash at Remondis Stadium.
