Luke has short turnaround to try to heal hamstring

After succumbing to hamstring tightness and missing the second half of Saturday's 46-12 loss to Manly, Issac Luke knows it's a challenge to prove his fitness for the Titans.

The experienced hooker managed only 41 minutes in Christchurch before leaving the field with the issue which he has been battling since the pre-season.

But he has little thought of self-preservation.

Speaking to NRL.com, Luke expressed regret at not staying on the park, even though he said it would likely have resulted in a full tear.

"I think I could have [played on], but if I did play on it probably would have torn," Luke said.

"I should have just played… I just want to be out there, if it tears it tears, you can't do anything about it.

"Hopefully if I'm not ready for next week I am ready for the week after."

With a six-day turnaround before facing the Gold Coast Titans in Auckland on Friday, Luke may be up against it to be declared fit. But he had some good news on his potential replacement in waiting, Nathaniel Roache, who has sat out the last two weeks with calf tightness.

"I think Nate ran yesterday so we will see how he pulls up [Sunday]," Luke said.

"I think we have got some [options at hooker]. Karl [Lawton] is there, Jazz [Tevaga] is there. Jazz does a fine job in there."

The loss in Christchurch means the Warriors have conceded 80 points in their last two NRL Telstra Premiership games, while they missed 41 tackles against Manly to go with 38 last week against the Wests Tigers.

The Warriors had no answer for Tom Trbojevic and Daly Cherry-Evans during Saturday's match, with the pair racking up four of their side's six line breaks, while the Sea Eagles also rolled through the middle of Warriors for 1,727 metres.

It prompted coach Stephen Kearney to question his side's mental toughness.  

"There's a bit of lack of resilience at the moment, which is an area of concern for us," Kearney said.

"To have 46 points tonight and 34 points last week. That's not good enough in the NRL. I thought given the situation on the back of last week and obviously the circumstance of the game, I was very disappointed with the effort.

"[On attack] it looked a bit like [we ran out of ideas]… that's my point with resilience, we just couldn't find a way to get over the line there.

"Lack of creativity, penetration and good ball."

Kearney also refused to be drawn on whether he would swing the selection axe ahead of round four, suggesting his current 17 have it in them to find form again.  

"It's too early to say that. I wasn't happy with the performance today, so whether that results in change, you will have to see over the next few days," Kearney said.

"As quickly as it changed from round one to round two it can change back. It's just getting back to what we know works for us."
