(Reuters) -World number one Carlos Alcaraz he has pulled out of the Davis Cup Finals in Bologna due to a swollen hamstring, he said on Tuesday, adding he was "heartbroken" to miss out.
The Spaniard aggravated the problem during the ATP Finals, where he lost to Jannik Sinner in Sunday's title clash, his withdrawal dealing another big blow to organisers the International Tennis Federation.
"I'm so sorry to announce that I won't be able to play for Spain in the Davis Cup in Bologna," Alcaraz said on Instagram.
"I have edema in my right hamstring and the medical recommendation is not to compete.
"I've always said that playing for Spain is the greatest thing there is, and I was really looking forward to helping us fight for the Davis Cup. I'm going home heartbroken."
Sinner, ranked number two in the world, pulled out of the tournament last month before defending champions Italy confirmed his absence.
Italy, who have won the past two Davis Cups, will also be without Lorenzo Musetti, who withdrew citing physical and family reasons.
Musetti's place is expected to be taken by Lorenzo Sonego who has been in Turin practising in recent days.
Italy will face Austria on Wednesday while Spain play the Czech Republic on Thursday in the quarter-finals with the final on Sunday.
