He might have been struggling to break into a decent stride last night, but Tuivasa-Sheck made it clear he'd be working around the clock to give himself every chance of being right for the club's first finals appearance since 2011.
"It's alright. I'm just icing and resting it and getting the swelling down," said Tuivasa-Sheck.
"I got tackled from behind and big Shannon Boyd squashed it. I think it's not too bad so I should be sweet.
"I'll just do whatever it takes. Firstly I'll go back and see the medical team and they'll let me know what I've got to do next. I'll do everything to try and get on the field."
Injuries have hampered the team throughout the season but coach Stephen Kearney is confident the Warriors will be at full-strength for week one of the playoffs.
Five-eighth Blake Green is ready to return from two weeks on the sidelines with a calf injury and front-rower James Gavet is also expected to slot back in after benefitting from a week's rest due to niggling calf and knee issues.
"We've battled through that all year and every team does," said Kearney.
"We'll monitor [Tuivasa-Sheck and Mannering] closely but my expectation is they'll be ready to play but we'll just see how they go. We'll give them every opportunity to play but just monitor how they pull up.
"Now that we know we're playing on Saturday, we have our week worked out in terms of training, so we'll just keep a close eye on them all."
Injury concerns aside, Tuivasa-Sheck is thrilled to have helped the Warriors returning to the finals and excited to have the opportunity for both he and the Warriors to measure themselves against the players and teams left in the premiership.
Having enjoyed a grand final win with the Sydney Roosters in just his second season in the NRL in 2013, he returned to the playoffs with the Tri-Colours in each of the next two years before joining the Warriors in 2016.
A season-ending ACL injury limited him to just seven games in his first year in Auckland, while his first season as Warriors captain saw the side drop to a disappointing 13th place finish last year.
"To come over here and take the Warriors into the playoffs and to do it back home where I grew up, it's exciting," he said.
"We're going to the playoffs, that's the big time, and you learn a lot from being in that situation, where the pressure and the expectations you have of yourself [are so high].
"I'm excited to go over there and see what we can do."
