Tennis superstar and 20-time grand slam champion Novak Djokovic lost his Olympic men’s singles semifinal to Germany’s Alexander Zverev 6-1, 3-6, 1-6.

This also ends the Serbian’s quest to achieve a “Golden Slam,” which is when a tennis player wins the Australian Open, French Open, Wimbledon, the US Open and the Olympics in one calendar year.

Steffi Graf, who did it in 1988, is the only player – male or female – to achieve the feat thus far.

Djokovic, a four-time Olympian, has never won a gold medal at the Games.

Djokovic and Spain’s Pablo Carreño Busta will fight it out for the bronze medal.
