Rafael Nadal arrived in London on Wednesday to begin his preparations for the ATP Finals.
Rafael Nadal has returned to practise in a boost to his hopes of featuring at the ATP Finals
The 33-year-old sustained an abdominal strain on Saturday, hours before he was due to play in the semi-finals of the Paris Masters.
He was ultimately forced to withdraw from the match which put his participation in the season-ending ATP Finals in major doubt.
But scans showed Nadal avoided a serious injury and he announced his plan to travel to London with the intention of playing at the O2 Arena.
And as promised the Spaniard wasted little time after arriving in England’s capital from Mallorca before hitting the practise court.
Nadal was spotted practising on the indoor courts at Queen’s Club with his coach Carlos Moya.
But in the footage posted on social media, the US Open champion appeared to be striking the ball with less intensity than he usually practises.
It is unclear whether Nadal worked on his serve but in his tweet on Tuesday, he suggested he would start serving again on Thursday or Friday.
How Nadal feels after serving will essentially determine whether he is able to play in the ATP Finals.
And he has until Monday night when he is scheduled to face Alexander Zverev in his opening match of the tournament.
Speaking in an interview with Spanish publication El Pais, Nadal’s long-time doctor Angel Ruiz Cotorro revealed they will wait until Saturday or Sunday before deciding whether to play.
“We will complete all phases and wait until the end,” he said.
“For now we can go there and start training. Day by day will tell us the possibilities you have of playing.
“On Saturday or Sunday we will know.”
If Nadal pulls out, his compatriot Roberto Bautista Agut will replace him in the tournament.
