Emma Raducanu ends this year's campaign and will keep her coach into the 2026 season.
Raducanu reached the third round in three out of four Grand Slam events this year.
Britain's Emma Raducanu has pulled out of the last two tournaments this season as a result of the illness that has affected her for the last week and a half.
The 22-year-old was scheduled to compete in Tokyo and Hong Kong but opted to return home to regain her health ahead of launching plans for the 2026 season.
Those preparations are set to feature her coach Francisco Roig, as both individuals have decided to continue collaborating in 2026.
She required blood pressure checks during her first-round match versus Ann Li in the Wuhan tournament and stopped playing when behind 6-1 4-1 on a day with extreme humidity.
Another medical visit was necessary medical attention at the Ningbo Open this week, where she lost in three sets to Zhu Lin, a Chinese wildcard in the opening round.
Raducanu was also moving noticeably restricted in the third set against Zhu due to back discomfort that has troubled her during parts of the season.
These outcomes meant an encouraging season, in which she climbed into the world's top 30 for the first time since her previous ranking, finished with a trio of defeats.
The athlete was close to victory with three match points prior to falling to Jessica Pegula in the third stage in Beijing last month.
The player achieved 28 matches in the current season and reached the semi-finals in the Washington tournament, but her most impressive week was at March's Miami Open.
As Britain's top player made the last eight of this WTA 1000 tournament, overcoming Emma Navarro, the eighth seed on the way prior to a loss in a three-set match to Pegula, ranked fourth.
She worked with Mark Petchey as coach from Miami until Wimbledon, with Francisco Roig stepping in in time for the US Open.
The original arrangement with the former trainer of Nadal was for the remainder of the year but they will keep working together, with planned training sessions for the end of the year.
She mentioned that her three-day trial with Roig post-Wimbledon was like a "secret mission" as they tried to keep the meeting secret.
She nearly succeeded to defeating top-ranked Aryna Sabalenka at the first competition with Roig in Cincinnati during August.
Roig was also with Raducanu in New York, where she made the third stage then falling to Elena Rybakina, the 2022 Wimbledon winner.
