Rafael Nadal had been on the road to meeting for a long time rival Roger Federer in their 39th career meeting in March in the last four of the Masters 1000 tournament in California.
But Nadal, who fought through his Indian Well's quarter-finals over Karen Khachanov, was forced to pull Federer into a walk-over winner due to pain in his right knee.
The 31-year-old sat out of the Miami Open referring to a hip problem and returned only a month later to the Monte Carlo champions, but Nadal could only reach the semi-finals in Monte Carlo, Barcelona and Madrid until he won the Italian Open in Rome and beats Novak Djokovic in the final.
Although he only won one of four build tournaments for the French Open, "King of Clay" was his dominant best back on Roland Garros and rolled aside Federer in the semi-finals in even sets before defeating Dominic Thiem in the tournament title showdown for another just years.
This triumph on the court Philippe-Chatrier saw Nadal become an 18-year-old Grand Slam champion, to move only two behind the entire record holder Federer and extend his unprecedented number of French open titles to 12.
But Nadal, reflecting on the disappointment of yet another injury blown, admitted that he was so miserable after his induced Indian Wells, that he was considering scrapping his 2019 calendar entirely from several fitness issues in recent years.
Asked if he hit a roadblock in front of the French open, Nadal told ATP Tour's official website: "It wasn't a roadblock – there are times you just have to make certain decisions. I've suffered a lot of damage during the last 18 months.
"If you refer to knee injury, which has given me problems, you can add a lot of other things that I would like to see setbacks that affected my game. Too many setbacks, honestly.
"I always push forward, but there's a point where you hit the bottom. Not being able to train or compete, it's frustrating, and it takes you toll on you.
"Mentally, after Indian Wells, I experienced a big decline. Ideas and scenarios swirled in my head.
"I was considering closing my season to see if my body would recover instead of playing through injury after injury. Another option was to tap and play through the pain.
"Whatever was the prospect gloomy, it required a change of mindset this time, and it doesn't happen overnight.
"I was reluctant and hesitant to return. Physically, due to another tendon drive in my knee and on top of all the treatment needed in the recovery process, it was the pain.
"This is the reality of the case – it was different this time. It usually doesn't work with me.
"Usually, the injury is diagnosed, I rehab, train and go through the routine as if it were nothing. I would play through pain and would not even consider it as a disorder.
"This time was different … considering my story of competing for battle. Normally, this process is not what I would consider" suffering ".
"Between the level of pain and straight sidelines, there came a time when I just felt tired of all this. I was sick of always having pain. I get it: with competing comes pain.
"But once you have accumulated injuries, decided to handle them, recovered from them, and before you even get back to the court you've acquired someone else who is taking a toll.
"After Indian Wells I took a moment to make sense of it all. I felt a little more optimistic about the time of the Rolex Monte Carlo Masters, but I was still in a very low place and hardly positive."
