Kodi Nikorima is in doubt for the Warriors' trip to Bankwest Stadium to face Parramatta after sitting out Tuesday's training session with an ankle injury he suffered in last Friday's victory over Cronulla.
Nikorima picked up the injury while scoring a crucial second-half try in the club's eventual 19-18 victory in Wellington.
While he finished the game, Nikorima was placed straight into a moon boot after the match.
Training at five-eighth on Tuesday was rookie Chanel Harris-Tavita, who served as coach Stephen Kearney's primary strike weapon off the bench over the past two weeks.
Chief playmaker Blake Green is certain the 20-year-old will fit straight back into the halves if required on Saturday against the Eels.
"He'll be fine. Good kid, knows what he's doing, had a couple of games there this year and did a really good job," Green said of Harris-Tavita.
"If he gets a chance this week he will be very good.
Tackle of the week: Round 18
"I think he's done a great job [off the interchange]. It's a difficult one because he can come on and sort of play any position and might only get the last 10 minutes, or get 40 minutes."
After overtaking Adam Keighran as the preferred No.6 at the club in round four, Harris-Tavita was relegated back to reserve grade when the Warriors signed Nikorima from the Broncos in May.
Injuries to front-line hookers Nathaniel Roache and Karl Lawton opened the door for Harris-Tavita's return earlier this month, albeit in an unfamiliar role.

"I'd never played hooker before until I came on [there] in Brisbane, and then Ken [Maumalo] got taken off, and I had never played wing or centre before [but had to]," Harris-Tavita said.
"I am just playing every position at the moment … it's been exciting, you don't know what to expect, but I am learning.
"It's good to be in other positions and to see what they see in a game, and then when you go back into your position [in the halves] you know what you want from them and it's easier to connect.
"It's still the start of the week so we will see how 'Kodes' pulls up, but if he doesn't play, I have been playing Canterbury Cup for the past seven weeks or so at half … I think I will be confident to be back in that role."
Lawton returned to training on Tuesday after sitting out the last two games with a shoulder injury, while Ken Maumalo (concussion) also took part after being a late withdrawal last weekend.
Jazz Tevaga on the other hand appeared to suffer another setback with his ongoing ankle injury and limped from the field near the end of the session.
Try of the week: Round 18
Following last week's win the Warriors have jumped to ninth position on the ladder and sit just one point outside the top eight.
Green said they head to Bankwest Stadium in good shape and with plenty of confidence.
"Of course we can be better, but there's a reason why we are sitting ninth on the table," Green said.
"We have had some gritty performances over the last 4-5 weeks.

"Two wins and a draw from our three road performances, it's been pretty pleasing.
"We have only not been able to finish one [game] in the last month, so we are finishing something alright.
"I think we have found the style of footy that works for us, we've found what we need to consistently be good at to be competitive enough in games to get the result.
"We have got miles of things we need to improve on, but one thing that's been consistent over this last patch of footy is just our effort for each other."
