Neymar's calf injury sustained in mid-May while with Santos has dominated recent developments, with a grade-two strain initially sidelining him for two to three weeks and raising doubts about Brazil's World Cup opener against Morocco. However, an MRI conducted days before the June 10 tournament start confirmed good progress within expected recovery timelines, and national team staff including coach Carlo Ancelotti have expressed optimism that the 34-year-old will return for the group stage or shortly thereafter. His inclusion on the official roster and history of overcoming prior knee setbacks further support the elevated implied probability for participation, as the Seleção prioritize his experience in a competitive Group C.
