Despite the tight deadline, he never doubted he would make it.
The only uncertainty came as he lined up his first tackle in a training game against the United States.
"To get a proper game under my belt and get some real contact on my shoulder gave me a shot of confidence," Curry told NZ Newswire.
"It was only then that I knew I was ready for the Olympics."
Curry's return adds size to what was already a towering squad as Tietjens tries to atone for a shortage of top-end speed.
Teddy Stanaway's tournament-ending injury in Florida opened the door for another lanky ball-winner in Lewis Ormond.
"I think size is how the game's gone now, the big players," Tietjens says.
"It's all about winning the contact, holding possession and if you can do that, you win games.
"Someone like Sonny Bill Williams is massive in contact, great at taking the ball up, great defensively, and that's what it takes."
Tietjens acknowledges a Fiji team motivated to win their country's first Olympic gold medal will start favourites.
However, his focus doesn't go much further than the opening games against Japan and Kenya on Wednesday NZ time.
A third pool fixture follows a day later against Great Britain, who boast nine Englishmen in their ranks, along with two Scots and one Welshman.
Later on Thursday are the quarter-finals which Tietjens expects to be of high quality given the stretched-out nature of the 12-team tournament.
