Napoli forward Victor Osimhen withdrew from training on Tuesday following an ankle injury.
The Partenopei announced that the Nigeria international left training prematurely due to the setback.
“Osimhen left training prematurely due to a sprain to his right ankle,” reads a statement on the club’s official website.
The 24-year-old, according to another report, sustained the injury after colliding with new signing Nathan during a practice match.
He was visibly pained as he limped off the pitch and instantly applied an ice pack to his ankle.
The striker is not expected to be out of action for a long time.
The 2023–24 Serie A season is expected to kick off on August 19.
The Partenopei will face newly promoted Frosinone in their opening fixture.
