The Volts will be missing four first-choice bowlers for its Super Smash game against Northern Districts in Hamilton today.
Wrist spinner Michael Rippon is the player with the sore bottom. He missed the tied match with Auckland with a stiff hamstring, but the injury has climbed to his glute.
He will be sidelined for the next week or so.
Matt Bacon is taking some time off due to the imminent arrival of his first child.
Leading seamers Jacob Duffy and Michael Rae have picked up Covid and have obviously been ruled out.
Batter Dale Phillips missed both games in Queenstown due to the virus and Volts coach Dion Ebrahim expects more Covid infections during the next few weeks.
"It was something we identified weeks ago, that with the amount of travel that we're doing and the places we are going, that the potential for Covid was a high probability," he said.
"We factored that all in and ensured that the players that weren't selected kept up their loading [to be ready] at the drop of a hat, so we planned for this."
All-rounder Beckham Wheeler-Greenall joins the side and replaces Rippon, while Jarrod McKay and Travis Muller will help plug the seam attack.
And hard-hitting left-hander Nick Kwant has been brought in as batting cover. He played seven T20s for Canterbury in 2017-18.
Wheeler-Greenall and Muller have played eight T20 games between them, but Jarrod McKay will be on debut.
Andrew Hazeldine is likely to get bumped up to the starting team. He made his debut for the province against Auckland in Queenstown and bowled well without success.
But he has only played two T20s as well, so Otago will field a very green team.
Otago's last outing against Northern Districts was unforgettable in a forgettable way .
The Volts made a catastrophic beginning of their innings.
They lost three wickets without adding a run between the second and fourth over.
They limped to 123 for eight. But that was not enough on a good batting surface in Queenstown.
The Brave cantered to victory with nearly five overs to spare.
But redemption is on offer in the return match at Seddon Park. Ebrahim said the side had addressed the nightmare three-over stretch.
"We all identified that we were slow to respond ... and we didn't adapt as quickly as we should have.
"But we have been very happy with the way we are trending."
Ebrahim said Otago had struggled to post scores of 150 or more in the two previous seasons, but the Volts had two scores of 150 plus and another of 144 in its four games this summer.
"So we are keeping a positive perspective on where we are at."
Dean Foxcroft has been a revelation with the ball as well as making an im-pact with the bat.
He has collected two half centuries and top-scored with 44 in the win against Auckland.
Those sorts of feat are expected, but not so his five for 11 against the Aces which was a career-high.
It was not a one-off performance, either. He has been consistently good.
He has nine wickets at an average of 8.88 and an economy rate of 5.
"I wouldn't say he's a revelation because we knew he is a smart and slick operator with the ball," Ebrahim said, but added no-one had expected him to have such a big impact with the ball.
