Neymar, 34, will miss Brazil's national team preparation matches for the World Cup due to a grade two muscle lesion in his right calf. The injury puts his participation in Brazil's debut match at risk, scheduled against Morocco on June 14.

The diagnosis was confirmed on Thursday by Rodrigo Lasmar, the doctor of the Brazilian Football Confederation (CBF). Lasmar's confirmation highlights the severity of Neymar's condition, which jeopardizes his readiness for the World Cup starting on June 11.

Neymar's absence from the preparation matches could affect Brazil's strategy and morale. The team must adapt quickly to the possibility of playing without one of their star players.

The Brazilian Football Confederation has not yet announced a replacement for Neymar in the preparation matches. The decision will depend on further medical evaluations and Neymar's recovery progress.

Neymar's injury history has been a concern for Brazil, especially in major tournaments. His current condition adds pressure on the team to find alternative strategies for the upcoming World Cup.
