Roger Federer will head into next week's US Open feeling optimistic he has overcome his injury concerns.
The Swiss, 36, struggled with a back problem as he lost to Alexander Zverev in Montreal two weeks ago.
But the third seed has been practising freely in New York and said: "I'm really happy how I'm feeling."
A hip injury has seen Andy Murray join Novak Djokovic, Stan Wawrinka, Milos Raonic and Kei Nishikori on the list of absentees.
That leaves Federer and top seed Rafael Nadal as the clear favourites, with the pair in line for a potential semi-final meeting.
