Hilton Cartwright will captain Western Australia in their Sheffield Shield clash with NSW in Sydney, after Mitch Marsh was ruled out through injury.
Cartwright becomes WA's third different skipper of the summer, with Marsh needing surgery after being hit in the groin in training.
It's a new setback for the 27-year-old, who has fallen out of the Australian side in all three formats this summer.
Marsh was hoping a strong end to the Shield season would boost his chances of an international recall, with Marcus Stoinis having recently overtaken him as Australia's preferred Test all-rounder.
Vice-captain Ashton Turner is in India on ODI duties with Australia, so former Test all-rounder Cartwright was called upon to lead the depleted Warriors in a team showing seven changes.
All-rounders Marcus Stoinis and D'Arcy Short as well as paceman Jhye Richardson are also on the India tour.
Marsh copped the hit while batting on Tuesday, and underwent a "minor surgical procedure" on Wednesday.
He may be available for the next Shield clash with South Australia at the WACA Ground starting on 3rd March.
WA are also without David Moody and Ashton Agar, who has a finger injury, while veteran batsman Jonathon Wells has been dropped despite his form with Adelaide Strikers in the Big Bash League.
Marsh's brother, left-hander Shaun, is missing due to a hamstring problem.
Rookie right-arm bowler Lance Morris could get his debut in an inexperienced pace attack alongside Matt Kelly and returning left-armer Joel Paris.
WA are fourth on the Shield ladder at the midway point of the season, three points behind the second-placed Blues.
Western Australia are 2.10 to beat NSW, who are 1.72.
WA are 7.50 to win the Sheffield Shield title.
