Overview
- The 19‑year‑old pulled out of the ATP 250 in Brisbane before his scheduled opener against Reilly Opelka, where he had been the sixth seed.
- Tournament officials will replace Fonseca in the draw with a lucky loser after his Sunday night first‑round slot was vacated.
- Live ranking calculations place him around No. 29 after the 125‑point drop, with the possibility of falling outside the top 30 when the list updates.
- His camp is targeting a return for the ATP 250 in Adelaide starting January 12, with the Australian Open beginning January 18 in Melbourne.
- A further slide outside the top 32 would jeopardize a seed at the Australian Open, increasing the risk of a tougher early draw.
