Pat Rafter has stepped down as Australian Davis Cup captain, with Lleyton Hewitt anointed as his long-term successor.
Wally Masur will officially captain Australia on an interim basis in the tie against the Czech Republic, with Rafter saying Hewitt will "fill the spot when the time is ready".
Hewitt plans to keep playing sparingly in 2015, focusing on the Cup and Wimbledon, with next year's Australian Open shaping as his likely swansong.
The 33-year-old father of three said finishing his career at Melbourne Park in a record 20th straight Open would be the perfect way to bow out.
"My body is fine. I think I train harder than anyone else in the off-season."
