Roger Federer has signed out for the ATP tournament in Dubai in the night from Thursday to Friday (Dutch time).
The Swiss is satisfied with his return to Doha, but notices that he needs more training hours.
Federer made his comeback in Doha on Wednesday after more than a year and did so with a victory over Briton Daniel Evans.
On Thursday he went down against the Georgian Nikoloz Basilashvili and not long after he decided to sign out for Dubai.
“It was great to be back and I loved every minute in Doha, but I have decided it is best to train instead of playing in Dubai,” Federer writes on Instagram.
Shortly after his loss to Basilashvili, the twenty-time Grand Slam winner also announced that he was happy with his long-awaited return.
"I am especially happy that I was able to play a few three-setters in a row against top players. I have taken an important step forward," he said.
"I am not yet 100 percent, I can feel that and I can see it in myself. It is important that I am later at the start of the grass season. I am still building up, so I see this as a springboard. I am generally happy with how I feel. "
The 39-year-old Federer is not the first big name to decide to abandon the Dubai hard court tournament.
On Thursday, Rafael Nadal decided to ignore the invitation for a wild card due to his back injury.
