Neymar's calf strain, a grade-two injury sustained in mid-May with Santos, has sidelined the 34-year-old forward from Brazil's World Cup opener against Morocco and recent friendlies, with medical staff projecting a two-to-three-week recovery window. Coach Carlo Ancelotti retained him in the 26-man roster, emphasizing ongoing positive progress in rehabilitation and targeting a return during the group stage, potentially as early as the match versus Haiti. This selection decision, combined with Neymar's prior ACL recovery and ongoing motivation in camp, underpins trader consensus around high implied probability for eventual participation, though his minutes and full fitness remain subject to match-by-match assessments in the tournament setting.
