Emma Raducanu ends the current season and plans to retain trainer into the 2026 season.
Raducanu reached the third round in three of the four Grand Slams this year.
Britain's Emma Raducanu will not compete in her remaining competitions in 2025 as a result of the illness that has affected her for the last week and a half.
At 22 years old had planned to participate in Tokyo and Hong Kong but has decided to fly home to rest and recuperate before starting next year's training.
These plans are set to feature trainer Francisco Roig, as they have decided to continue collaborating for the upcoming season.
Raducanu underwent blood pressure monitoring in her opening round against Ann Li in Wuhan last week and retired when losing 6-1 4-1 on a day with extreme humidity.
She again required a doctor's assessment at this week's Ningbo Open, where she fell in a three-set match to Zhu Lin, a Chinese wildcard in the opening round.
She was also playing noticeably restricted in the deciding set against Zhu because of a lower back issue that has troubled her at times this year.
Such performances followed a positive campaign, in which she climbed into the international top 30 after more than three years since her previous ranking, ended with three successive defeats.
She held three match points before losing to American player Jessica Pegula in the third stage in last month's Beijing event.
The player achieved twenty-eight matches during 2025 and made it to the semi-final round in Washington, but her standout performance was at the Miami event in March.
The British number one made the last eight of a premier WTA event, overcoming Emma Navarro, the eighth seed en route then falling in a three-set match to the world number four Pegula.
She worked with Mark Petchey as coach from the Miami event through Wimbledon, with Francisco Roig stepping in for the US Open.
The original arrangement with the ex-coach of Rafael Nadal was until the end of the season but the partnership will continue, with a training session scheduled late this year.
The athlete revealed that a three-day test period alongside Roig after Wimbledon was like a "secret mission" as they tried to keep the meeting secret.
The player was close to beating world number one Aryna Sabalenka at their first tournament together in Cincinnati in August.
The coach also accompanied Raducanu in the New York tournament, where she reached the third round then falling to 2022 Wimbledon champion Elena Rybakina.
