England captain Nat Sciver-Brunt has been passed fit to return from injury for Thursday’s T20 World Cup semi-final against South Africa.

Sciver-Brunt, 33, who has not played since England’s second match of the tournament against Ireland after a recurrence of her calf issue, batted in the nets again on Wednesday morning.

She also trained on Tuesday at Lord’s and England have deemed her fit enough to return as her side attempts to win a World Cup for the first time since 2017.

“We are confident I am fully fit,” Sciver-Brunt told BBC Test Match Special.

Sciver-Brunt, who has used rare magnetic resonance therapy to help regain her fitness, is likely to replace Sophia Dunkley in England’s XI.

Batter Dunkley was seen in conversation with coach Charlotte Edwards shortly before Sciver-Brunt emerged to speak to the media.

While Sciver-Brunt batted for half an hour on Wednesday, appearing relatively free and able to come down the pitch to spinners, there are obvious risks involved.

She worked with England’s physio indoors at the start of the session but did not do any running or fielding drills outdoors.

There are less than 72 hours before Sunday’s final.

“We have tested it enough to be comfortable,” she said. “What will happen out on the pitch will happen.”

Assuming she comes through, Sciver-Brunt’s presence for the latter stages is a significant boost to England.

She is their best batter and, though Charlie Dean has stood up successfully in her absence, their captain. Sciver-Brunt, Heather Knight and Danni Wyatt-Hodge are the only players remaining from their last World Cup win.

England have lost their last two World Cup semi-finals against South Africa – at last year’s 50-over World Cup and the T20 version in 2023 – but go into Thursday’s match at The Oval as favourites, having progressed through the group stage unbeaten. They have also never lost a women’s international at The Oval.

South Africa have been unconvincing at times during this tournament, but have reached the past three World Cup finals across formats as they chase their first World Cup win.

And captain Laura Wolvaardt admitted her batting line-up – blessed with powerful strokemakers such as Tazmin Brits, Nadine de Klerk, Marizanne Kapp and Wolvaardt – has not been at “100%” and it has been “frustrating” they were not able to win games more comfortably.

“We have chatted about it, that if we do find ourselves in a position to kill the game earlier we are blessed with a lot of power in our line-up,” she said.

“We have that opportunity to go a bit earlier. Maybe tomorrow at The Oval suits us a bit better.”

Wolvaardt also swerved a question on whether she would be happy for Sciver-Brunt to have a substitute fielder, should the England captain injure her calf again.

Cricket’s laws state substitutes are allowed to replace players who suffer an injury during a match, rather than an issue carried in.

“As a captain it is always hard to plan for her,” Wolvaardt added.

“She is a world-class batter and is able to hit really weird areas.

“Setting a field is quite hard for her. Hopefully we are able to keep her quiet.”
