Overview
- The 19-year-old pulled out of the Adelaide ATP 250 after earlier withdrawing from Brisbane due to persistent back pain.
- Fonseca described the issue as a chronic condition tied to a congenital problem, noting a prior stress fracture five years ago.
- He said scans indicated no major damage but warned it could worsen, stressing he will only compete when he feels 100 percent.
- His participation in the Australian Open, which begins January 18, remains undecided as he focuses on recovery.
- He has not played since the Paris Masters loss to Karen Khachanov and is reported around No. 30 in live rankings, which would make him a seed if he plays in Melbourne.
