The 39-year-old Serbian, who just celebrated his birthday last week, experienced a rare defeat in Paris, prompting speculation about his future participation in the tournament after 22 consecutive appearances.
”I don’t know,” the world number four replied when asked about the possibility of competing at Roland Garros again.
Djokovic, who has been dealing with an injury for three months, mentioned that he felt he played ”really good tennis” against Fonseca but was exhausted by the end of what will be recorded as his longest match in the French Open at four hours and 53 minutes.
”There were moments when I felt like I could barely stand on my legs towards the end of the match,” the 24-time Grand Slam champion shared.
This marked the second time Djokovic lost after being up two sets, the first instance also occurring at Roland Garros against Jurgen Melzer in 2010.
If Djokovic decides to return, he would join a select group of players participating in the French Open at the age of 40, a rare achievement in the Open Era.
