Warriors captain Tohu Harris is taking a wait and see approach to a knee injury that forced him out of his side's dramatic win over Cronulla.
Harris suffered his injury during the first half of the round-four victory over Canterbury, and while he took part in a light training at Mt Smart Stadium on Wednesday the lock wouldn't confirm if he'll take his place against Newcastle at McDonald Jones Stadium on Sunday.
"The knee is going alright," Harris said.
"I'm just ticking the boxes as they come along and trying to give myself every opportunity to get back on the field. It's too hard to call at the moment but I'm very optimistic.
"It was hard watching the game on the weekend, so I just want to be out there on the field with the boys. But I have to make sure I'm doing the right things."
Harris wasn't the only one living and dying on every play, watching his side pull off a 32-30 win at Shark Park after another slow start had them down 26-12 at halftime.
The Warriors' hot form has seen interest surge in Auckland, with early predictions pointing to a near sell out for their next home match against North Queensland.
"It was definitely a roller coaster. We haven't started well in every single game this year and against the Sharks it went on for a longer period," Harris said.
"We just weren't playing how we've trained. We saw a few things we haven't seen since pre-season that we've quickly tried to get out of our game, hopefully we can get back and fix those fundamental things.
"Like I said, it was like a roller coaster - and I don't like roller coasters."
It will be the second time the Warriors and Knights have met this season, after the Kiwi club triumphed 20-12 in round one.
"Newcastle's found some form and they'll be a tough opposition," Harris added.
"Your preparation affects every game you play. We're trying to make the most of our time before we travel away, and I'm sure Newcastle's doing the same.
"They've found confidence and are scoring a lot of points. It's certainly going to be a tough game."
Warriors head coach Andrew Webster said that Harris "knows his body and I trust his decision."
"Right now it's in the balance. It could be in the balance next week or the week after.
"That's just the way these injuries are unfortunately."
Meanwhile, there are no such complaints around five-eighth Te Maire Martin who sat out the Cronulla clash after a concussion.
"I'm back to normal," Martin said.
"I wasn't actually too bad during that game anyway. Parts of it are a bit patchy but otherwise I'm sweet."
Martin shared the emotion of his skipper watching the win against the Sharks unfold on TV.
"It's the most nervous I've ever been," he said.
"To come away with that win is a true testament to that character of the team, it's unreal."
