Luke suffered a calf strain during New Zealand’s loss to Melbourne last weekend, while Harris has been named for the first time in a month after picking up a knee injury in round 16.
Speaking to the media in the build up to Sunday’s contest, Warriors coach Stephen Kearney said the pair would be game-time decisions.
“We’ll see how they get through tonight, how they pull up (from Thursday afternoon’s training session),” Kearney said.
“We’ll make a decision on those two guys by Friday. We fly [on Friday] so we’ll have to make it (a decision) by [Friday].”
“I’m worried about Sunday. We’ll worry about next week, next week.”
