Federer, who made a late decision to attend this year's Laver Cup in Boston -- a tournament held between teams from Europe and the rest of the world -- said on the sidelines of the event that the recovery and rehabilitation are "going to take me a few more months and then we'll see how things are at some point next year".

"I just wanted to give you a bit of an update [on] what's been going on since Wimbledon. As you can imagine, it's not been simple. I've been doing a lot of checks with the doctors as well on my knee, getting all the information as I hurt myself further during the grass-court season and Wimbledon," Federer said in a video posted late on Sunday, which was also put up on atptour.com.

He came back to win the fourth 6-2 in a games that lasted two hours and 44 minutes. World No. 41 Mannarino, who was able to get through to the fourth set with the injury before pulling out, had slipped behind the baseline which led to the injury. He also received on-court treatment on the knee.

"The good thing now, looking back, is I know it will not happen here because I am ready, I am excited. I am pumped up. I know I can do so much better," said Federer, who lost early at the Geneva Open, exited after the fourth round of French Open due to injury and lost in the second round of Halle Open.

The Swiss ace, who has won the Halle trophy a record 10 times, was being challenged by 20-year-old Auger-Aliassime for the first time. But, despite the age difference -- 19 years, as both share their birthdays on August 8 -- the Canadian displayed maturity beyond his age to defeat his "childhood idol". This was Auger-Aliassime's fourth top-10 career win and will next face the winner of the match between Germany's Jan-Lennard Struff.
