It comes after losing in the third round at Indian Wells, top-ranked athlete Novak announced he would skip the Miami Open this year.

The Serbian player announced his decision on Saturday following his 6-4, 3-5, 6-3 defeat to No 123 Luca Nardi at the BNP Paribas Open on Monday.

Nardi, 20, became the lowest-ranked player to beat Djokovic in a Grand Slam or ATP Masters 1000 level event. 

The last player to hold the feat was No. 122 Kevin Anderson in Miami in 2008.

'Unfortunately I won't be playing the Miami Open this year,' Djokovic wrote. 'At this stage of my career, I'm balancing my private and professional schedule.

'I'm sorry that I won't experience some of the best and most passionate fans in the world. I'm looking fw competing in MI in future!'

Before losing to Nardi, Djokovic secured a 6-2, 5-7, 6-3 win over Aleksandar Vukic in the second round.

Nardi got into the field as a 'lucky loser' - the title used for players who stumble in qualifying rounds but enter the main draw by replacing a player who pulls out before the first round.

Despite sitting out the tournament this year, Djokovic has won the Miami Open six times. The hard-court tournament will begin next week.

After winning seven singles titles in 2023, Djokovic is still searching for his first championship this year to add to the 98 in his career.

Novak is married to wife Jelena. The pair have two children, Stefan, born in 2014, and Tara, born in 2017.

They first met at their Serbian high school in the late 90s, however, they didn't officially start dating until 2005.

The pair got engaged in September 2013 and officially tied the knot back in July 2014.

The wedding was held at Aman Sveti Stefani in 2014, just days after Novak won his second Wimbledon title.
