Rafael Nadal reveals what actually went wrong in Olympic doubles defeat with Jannik sinner…

Jannik Sinner is on course to return to action at the Canadian Open as the defending champion has recovered from his recent illness, but there are question marks over the participation of several top ATP stars at the Masters 1000 event in Montreal.

World No 1 Sinner has not competed since losing in the quarter-final at Wimbledon as he first withdrew from the Swedish Open due to fatigue and he then pulled out of Italy’s Olympic squad as he was “strongly advised” by doctors to skip the Paris Games due to illness.

“I am saddened to inform you that unfortunately I will not be able to participate in the Paris Olympic Games,” he wrote.

“After a good week of clay training I started to feel unwell. I spent a couple of days resting and during a visit the doctor found tonsillitis and strongly advised me against playing.

“Missing the Games is a huge disappointment as it was one of my main goals for this season.”

The reigning Australian Open champion appears to be 100% again as he has arrived in Montreal for the ATP Masters 1000 event and has returned to the practice court.

“Good to start hitting again and looking forward to building from here,” he said in a post.

Sinner, who defeated Alex de Minaur in last year’s final, will be the top seed for his title defence, but it remains to be seen who will be second seed as the event could still be hit by several withdrawals due to Paris Olympics.
