When preparing the BrisbaneATPIn Australia, João Fonseca He suffered a lower back injury and chose to withdraw from the tournament. The tennis player would face the American Reilly Opelka. Despite this, the Brazilian is expected to recover for the Adelaide ATPwhich begins on January 12. Due to his withdrawal, the 19-year-old could lose a few places in the world rankings.
ATP ranking scoring works on a 52-week system. This means that the results obtained the previous year must be “defended” the same week of the following year. When an athlete cannot participate in a tournament in which he or she had accumulated significant points, those points are automatically removed from the total, resulting in a drop in ranking.
This is what could happen with João Fonseca. Champion of Canberra Challenger last year it will drop 125 points and may drop out of the top 30 in the latest list update. In the current scenario, the position around 24th place was supported, in part, by impressive results in smaller tournaments, such as Challengers, in addition to campaigns in ATP events.

João Fonseca and the 2026 agenda
Even with the setback in his lower back, João’s planning for the first months of 2026 remains intense. We therefore expect a recovery in time for ATP 250 Adelaidescheduled between January 12 and 17, a tournament which serves as direct preparation for the Australian Openscheduled from January 18 to February 1. This first part of the season is therefore essential to gain rhythm on fast terrain.
In this scenario, the planning provides for participation in eight of the nine tournaments of the Masters 1000 series, in addition to five events of the ATP 500 category. The rule allows Monte Carlo, in April, to be the only Masters 1000 outside the mandatory calendar. Thus, these commitments are added to the four Grand Slams and the competitions of Davis Cupbuilding a season in which physical and mental management become important.
