The 33-year-old began showing symptoms on Thursday and was immediately removed from team activities.

Medical tests later confirmed the viral infection, the Brazil Serie A side said today.

The club did not disclose how long Neymar will be out of action and did not immediately respond to a Reuters request for comment.

Neymar is already ruled out of Thursday’s league match at Fortaleza through suspension.

The Fortaleza match will be Santos’ last outing before the Brazilian league pauses for the June 14-July 13 Club World Cup in the US.

The former Barcelona forward’s future at Santos remains undecided, with his contract set to expire on June 30.

Limited by injury, he has made 12 appearances for Santos across all competitions this season, contributing three goals and three assists.
