Grigor Dimitrov will be returning to the match court for the first time since Wimbledon, while a Grand Slam champion will be departing for the last time.
Dimitrov suffered a heartbreaking pectoral injury at Wimbledon earlier this year, in a match where he led eventual champion Jannik Sinner.
This injury forced the Bulgarian to miss the US Open, and Dimitrov has even changed his coaching team in his time away from the ATP Tour.
Dimitrov was confirmed to play singles at the Paris Masters, but he will also feature in the doubles draw alongside a retiring Grand Slam champion.
Grigor Dimitrov to partner Nicolas Mahut at the Paris Masters
Dimitrov has only played two doubles tournaments in 2025, but has made an exception at the Paris Masters for Nicolas Mahut, the French player who will be retiring at his home ATP 1000 tournament.
Mahut, who is now 43 years old, is a former doubles world number one, and has won five Grand Slam doubles titles in his career.
All five of these major victories have come alongside his compatriot Pierre-Hugues Herbert, who Mahut has played four of eight tournaments with in 2025, including his most recent in Basel.
This has left some tennis fans confused, as many were expecting Mahut and Herbert to have one last tournament together in Paris.
While Mahut and Dimitrov have played together before, the Paris Masters will be only their third tournament as a pairing and first since 2023.
In what could be the final match of Mahut’s career, he will play alongside Dimitrov in the first round of the doubles draw against the pairing of Edouard Roger-Vasselin and Hugo Nys.
How did Nicolas Mahut make history at Wimbledon?
While Mahut has collected more success on the doubles court, he has also enjoyed a respectable singles career as well.
With a career-high singles ranking of world number 37, Mahut also won four career titles and achieved a best Grand Slam result at Wimbledon in 2016 when he reached the fourth round.
However, perhaps Mahut’s most famous moment came at Wimbledon in 2010, when he was part of the longest tennis match in history.
Playing against fellow big server John Isner, Mahut was beaten, 6-4 3-6 7-6(7) 6(3)-7 70-68, in a match that lasted 11 hours and 5 minutes, and took place over three days.
There is now a plaque outside Court 18 at Wimbledon to commemorate this match, and it was a big factor in the decision to introduce fifth set tie-breaks at Grand Slams.
