"But he's trained well since then and will certainly be given every opportunity to play this weekend."
At Tuesday's training Kearney said he was "pretty confident" about Luke's potential involvement, but he will no doubt take a cautious approach with the veteran.
A fit and firing Luke is vital for the Warriors; not only for the experience he adds to the spine, but also for the attacking flair he can bring to the team, given the absence of Shaun Johnson.
Australian Karl Lawton had a strong return to first grade against the Gold Coast side, and showed the value of a specialist in the No 9 jersey, and he is named to start again.
Nathaniel Roache remains out of the picture, after picking up a calf strain a day before the Tigers clash in Sydney. Kearney wouldn't specify how much longer he would be out for, only to say he was unavailable this week.
Chanel Harris-Tavita has been retained in the No 6 jersey, after an solid NRL debut last Friday. The 20-year-old showed a willingness to run with ball in hand, set up one try and made a line break to later put the Warriors in a promising attacking position. He also nailed his goal kicking responsibilities, and made 21 tackles in a busy display.
However Kearney was tempering any excitement about the local product.
"He did a okay job," Kearney told D'arcy Waldegrave on Radio Sport. "He executed his role pretty well and I was pleased he was able to do that. But he was the recipient of a pretty good team performance."
When asked on the improvements he was looking for from the Pakuranga Jaguars junior, Kearney said he wanted Harris-Tavita to take some load off Blake Green with more involvement in general play, particularly kicking.
Kearney also said the Junior Kiwi representative needed to brace himself for a increased defensive workload, with the Rabbitohs' power and size out wide.
Saturday's clash against the Rabbitohs will be the first NRL fixture played at Sunshine Coast Stadium.
The Warriors have struggled against the Rabbitohs in recent years — with some heavy defeats — but were victorious the last time the two teams met in Australia, with a 32-20 win in Perth last March.
Wayne Bennett's team have started the season well, with eye-catching wins over the Roosters and Dragons, while there only defeat so far was a golden point loss to the Sea Eagles last weekend.
Kick-off on Saturday is at 5pm (NZT).
