Rafael Nadal is taking some time off after his Australian Open final loss to Roger Federer.
The Spanish tennis federation has left Nadal out of Spain's Davis Cup team to face Croatia because of fatigue following his five-set loss to Federer.
He will be replaced with Feliciano Lopez for the first round of the World Group.
The decision was made after a recommendation by doctors, who said Nadal's recovery time would be too short.
The 14-time Grand Slam champion is expected to return to action in Rotterdam next month.
However, Roger Federer has ruled out skipping the French Open to save himself for Wimbledon as he hunts down more major silverware.
The resurgent Swiss has made it clear he won't be playing on for second prizes after being buoyed by his return to the top 10 in the wake of his unexpected Australian Open triumph.
The rankings boost will allow him to pick and choose a lighter schedule in 2017 without worrying about chasing points to retain seeding status at the big events.
