Carlos Alcaraz has announced he will not participate in next week's Madrid Open.
The seven-time Grand Slam winner withdrew from the Barcelona Open this week with a wrist injury and now joins Novak Djokovic in missing out on the tournament in the Spanish capital.
"There is some news that's incredibly difficult to deliver," Alcaraz wrote on Instagram.
"Madrid is home, one of the most special places on the calendar for me, and that's why it hurts so much not to be able to play here for the second year in a row.
"It hurts especially not to be able to be in front of my fans, in a tournament that's so special to me. Thank you for your continued support, and I hope to see you soon."
Djokovic has not competed since losing to Britain's Jack Draper in the fourth round in Indian Wells last month.
The 24-time grand slam winner subsequently withdrew from Masters 1000 events in Miami and Monte Carlo with a right shoulder problem, and he is not yet ready to return.
Writing on Instagram, Djokovic said: "Madrid, unfortunately I won't be able to compete this year. I'm continuing my recovery in order to be back soon."
Draper is also in a race to be fit for the event having retired during his first match in Barcelona this week with a knee injury.
