Australia spinner Adam Zampa is confident he'll be fit for the challenge of trying to take down power hitter Heinrich Klaasen during the upcoming five-match ODI series against South Africa.
Zampa played just one match of the recent 3-0 T20 series whitewash against South Africa.
He missed the series opener through illness, and he injured his neck in the warm-up to game two.
The 31-year-old fought through the discomfort to take his place in the side for that match, but he returned disappointing figures of 0-42.
Zampa was ruled out of game three as a precaution, but he's on track to play in the series-opening one-dayer in Bloemfontein on Thursday.
"It's an ongoing process. I'm sure it will be fine for the first game," Zampa said of the injury.
"I had a bit of a viral infection when I first arrived, and then probably pushed it, and the body wasn't ready.
"I'll be OK for the first game I think."
Australia thrashed the Proteas in each of the three T20 encounters.
But with the hosts bolstered by the return of rested stars Quinton de Kock, David Miller, Kagiso Rabada, Klaasen, and Anrich Nortje for the ODI series, Australia are bracing themselves for a tough challenge.
Klaasen looms as a big weapon for South Africa, with his class against spin and ability to hit big sixes set to play a key during the upcoming series.
"He's a big challenge. He's probably even more of a challenge now than he was a few years ago," Zampa said.
"He's one of the best players in the world at the moment.
"I played him at The Oval in The Hundred and saw it first hand.
"He's a pretty special player, so it's going to be a big challenge."
Australia are still without captain Pat Cummins (wrist), veteran Steve Smith (wrist) and paceman Mitchell Starc (groin), but David Warner returns.
Warner will be aiming to secure his spot at the top of the order ahead of the ODI World Cup in India, which starts on October 5.
Mitch Marsh, who was man-of-the-series in the T20 series against South Africa, will again captain the side.
