"I just have to get the timing of that reintroduction right."
Ropati travelled with the team to Manly last weekend when he was 18th man and trained at right centre during the week - he has largely been used throughout his 140-game career as a left centre alongside Manu Vatuvei.
Youngster Konrad Hurrell's value on attack is unquestionable - he's the club's second-top try-scorer and often busts the line - but he's also vulnerable defensively and opposition teams have often targeted the right edge.
The mental battle has been as big as the physical one for Ropati over the past couple of seasons but he said he felt two weeks ago that he was ready to return to the NRL and was preparing in the expectation he would play on Sunday.
"Prior to [two weeks ago] I was playing Vulcans and didn't think I was up to scratch," he said. "It wasn't until we played Wentworthville that the body felt good, up to pace.
"I'm in good shape right now and the mind is quite at ease. It's a different challenge at this time of year for me because I could be put into the squad at a really crucial time of the year."
The Warriors probably need to win all four of their remaining games to sneak into the playoffs, starting with Sunday's match against Penrith.
The Panthers come into the game on the back of a four-game losing streak - they have lost the past four by a combined total of 148-32 - and the Warriors will be expected to win.
Ropati has had discussions with the club about his future, although he wouldn't divulge what they were about, and how he fares over the coming weeks could have a bearing on what happens.
He offers a lot off the field, and the club might consider employing him in an off-field role after his playing career. He is a good player when fit but it's hard to escape his run of major injuries over the past two years.
"I haven't made up my mind just yet but I'm leaning towards [playing again next year]," he said.
"[The next four weeks] will confirm a lot of things I have in my mind about what I want to do next year."
