The list, released by the Nigerian Football Federation, includes four uncapped players plus five more who made a first international appearance just over a week ago in a friendly against Mexico.
Keshi has a settled look about his defence but has made a host of changes in other departments with Victor Moses and Emmanuel Emenike, who played key parts in the surprise Nations Cup Success in South Africa, unavailable.
Captain Joseph Yobo, dropped during the African Nations Cup, is left out as his international career looks to be at an end, while the likes of Peter Odemwingie and Obafemi Martins were again overlooked.
Keshi was pilloried by local media before the Nations Cup for choosing inexperienced, home-based players but since winning the continental championship has silenced the critics.
Nigeria are in Group B along with Tahiti, Uruguay and Spain for the Confederations Cup, which runs from June 15 to 30.
Before heading to Brazil, they travel to Namibia for a World Cup qualifier in Windhoek on Wednesday.
