Alcaraz, the defending champion at New York, exited this year’s final major after suffering a defeat to third seed Daniil Medvedev of Russia on Friday.

Alcaraz, 20, will be replaced by Albert Ramos-Vinolas in the Spain squad.

“I was really looking forward to playing for Spain at the Davis Cup in Valencia, but I have to listen to my body after a very long tour,” Alcaraz said on messaging platform X, formerly known as Twitter.

“I need to stop and rest, physically and mentally. The schedule is very demanding; there is still a long season ahead, and now it’s time to recharge my batteries. Best of luck to the Spanish team! I will be supporting you strongly! Let’s go!”

The 35-year-old Ramos-Vinolas, currently ranked 88th, has been called up by captain David Ferrer, who won the Davis Cup as a player on three occasions with Spain, lifting the trophy in 2008, 2009, and 2011, and finished as a runner-up in 2012.

“Ramos was already called up for last year’s Final eight in Malaga. This year he has been a finalist in Gstaad and a semifinalist in Cordoba, as well as reaching the quarterfinals in Rio de Janeiro and the ATP Challenger in Parma,” the country’s tennis federation (RFET) said in a statement.

“In Davis Cup, he has played five Davis Cup ties with a record of six wins and only two defeats.”

Sixteen teams will compete in the group stage from Sept 12-17 across Bologna, Manchester, Valencia, and Split. The top two teams from each group will qualify for the knockout stages from Nov 21-26 in Malaga.

Spain will play Serbia, the Czech Republic, and South Korea in Group C in Valencia.
