Mitchell Starc has shrugged off the suggestion of an injury as he prepares for Australia's final-day push to secure a series win against India at the Gabba.
The left-arm quick appeared troubled by a hamstring niggle in his only over as rain stopped play on day four.
India are 0-4 after being set a would-be record at the ground of 328 runs to win the game and the series.
Starc declared himself good to go on Tuesday morning though, saying any grimacing was simply the result of playing all four Tests this series.
"I'm OK, the four of us (fast bowlers) have played all four Test matches this series which is something that the other team haven't gotten through," he told ABC Sport.
"That's a credit to our change room for being quite robust and resilient."
Australia bowled 131 overs in the fourth innings in Sydney last week but took just five wickets as India's batters defied them for a draw.
Starc expects any repeat of that in Brisbane from the visitors to be much trickier given the behaviour of a cracking Gabba wicket on Monday.
"Sydney was pretty flat ... it didn't play too many tricks ... here at the Gabba we see that extra bounce and the one that Smithy (Steve Smith) copped off a length ... it's what we're after and it makes for a really exciting last day," he said.
"They certainly have the batting line-up to chase this down if they want to... But the wicket's offering enough that we should at least be able to create 10 chances."
