Australia's one-day wicketkeeper Matthew Wade will make his Test debut next month following Brad Haddin's decision not to return for the series against the West Indies.
Haddin had left the tour early to return home for family reasons, but was expected to return for the three-Test series.
But Cricket Australia announced that Haddin's New South Wales deputy, Peter Nevill, would remain in the West Indies as Wade's understudy.
"Cricket Australia fully supports Brad's decision to remain in Australia and sends its best wishes to him and his family at this time," Telegraph.com.au quoted Cricket Australia team performance manager Pat Howard, as saying.
While Haddin, 34, lost his place to Wade in the one-day side this summer, the selectors stressed that Haddin remained the incumbent Test keeper.
With Wade now set to play in the Test series, Haddin's international future remains unclear.
Wade's strong record for Victoria suggests he is ready to step up to Test cricket.
He has already played 50 first-class matches, averaging 40, with four centuries, and also has four hundreds and an average of 36 in domestic one-day cricket, while Haddin has struggled with bat and gloves of late, with his Test average falling from a career-high 43 to 36.
Pattinson gets T20 berth for Windies series
Meanwhile Australian pacer James Pattinson will make his first appearance in the West Indies after being named in the Twenty 20 squad.
Pattinson was named in the side for the first T20 match, along with allrounder Dan Christian, which are the only changes made in the squad that won the final one-dayer by 30 runs.
Pattinson, 21,had earlier been ruled out of cricket after suffering a buttock muscle strain in the one-day final against Sri Lanka in Adelaide earlier this month.
Christian makes a comeback into the side after being dropped for two one-dayers.
Australian Twenty20 captain George Bailey said his team's biggest challenge will be to tackle allrounders Darren Sammy, Kieron Pollard and Andre Russell after their stellar performances in the ODIs.
"They've got some enormous strikers of the ball, pure hitters. We've talked about a few ways to try and defuse that, a few different things to focus on but I think one of the inevitabilities of Twenty20 is you're going to bowl balls that are going to get hit. Most importantly it's about how you can respond to that," The Sydney Morning Herald quoted Bailey, as saying.
Australia: Shane Watson, David Warner, Matthew Wade, George Bailey (capt), Michael Hussey, David Hussey, Dan Christian, Brett Lee, James Pattinson, Clint McKay, Xavier Doherty, Nathan Lyon (12th man).
