PARIS — It’s entirely possible that Novak Djokovic and Rafael Nadal, two of the greatest players in history, will meet in the second round of the men’s tennis tournament at the Summer Olympic Games.

And that could well be the final singles match of the legendary Nadal’s illustrious career.

The great Spaniard chose to come to the clay courts of Roland Garros, where he has won 14 French Opens, to celebrate the end of his magnificent career and possibly play for the last time.
