- Fonseca pulled out of his Cincinnati match with abdominal pain, returned to Rio de Janeiro for tests and treatment, and has not disclosed precise medical details or a return timetable.
- His exit is the latest high‑ranked pre‑tournament absence and is the third top‑30 withdrawal to alter the men's draw after other players missed the event with injuries.
- The 19‑year‑old rose to world No.26 this season with quarter‑final runs at several big events and had been seen as a rising contender at Grand Slams.
- Tournament officials and players face renewed scrutiny over scheduling, medical transparency and how late withdrawals reshape seeding and competitive balance.
