Fifth-ranked David Ferrer is set to play singles alongside Nadal, while Feliciano Lopez and Fernando Verdasco should team-up for doubles.
Spain captain Albert Costa has also included Marcel Granollers and Marc Lopez as playing partners. Granollers is coming off a victory at the Valencia Open.
The four-time champions begin training in Seville on Saturday, with Nadal and Ferrer joining up after the ATP World Tour Finals.
