Paul Stirling, the Ireland batter, will replace New Zealand's Devon Conway at Southern Brave, and the availability of Wahab Riaz, the Pakistan quick, for the Trent Rockets means their South African recruit Marchant de Lange will leave the men's Hundred after four matches and return to Somerset for their Royal London One-Day Cup campaign.
Conway, also a Somerset man and one of the more prominent newcomers at the international stage, had a steady run with Brave in the Hundred, getting starts on each occasion. He had scores of 18, 23, 34 and 22 for a tally of 97 runs, scored at a strike rate of 112.79. But in that last game, against London Spirit at Lord's, Conway took a blow from a Blake Cullen delivery in the fingers of his left hand very early in his innings, and while he finished his innings, he didn't come out to field.
Stirling, the veteran batter, wasn't at his best when he turned out for Ireland during South Africa's visit in July for a set of ODIs and T20Is, but brings with him a wealth of experience. Not to forget the exceptional form he was in earlier this year in Abu Dhabi, when he scored ODI centuries against UAE and Afghanistan.
de Lange, meanwhile, was one of the bowling stars of the competition, the joint-leading wicket-taker after the first 17 matches with eight wickets, the same as Northern Superchargers' Adil Rashid and the Rockets' Rashid Khan.
But the Rockets will welcome back their original pick, Riaz, whose participation in the Hundred had been delayed after he reached the UK because of an issue with his visa - he didn't have a valid work permit - which forced him to fly home, sort it out, and then return to link up with his team. He has completed his mandatory quarantine on his return to the UK, and is available for the Rockets' next fixture, against Welsh Fire on Friday in Cardiff.
The Rockets have had the better time of it at the tournament so far, three wins in four outings giving them a top-of-the-table spot with six points, while Brave are in the other half of the eight-team table, down at seventh place with four points from four games, only above Spirit.
