Barcelona forward Ansu Fati injured his hip in training on Friday and is set to miss the first friendly of pre-season against Gimnastic on Saturday, APA-Sport reports.
A Barça statement said: "LATEST NEWS Ansu Fati has a right hip contusion, which he suffered during Friday’s training session. He is out and his recovery will determine his availability."
Ansu, 17, returned to training this week following a week away with the Spain national side, where he became the country's youngest ever goalscorer.
He is set to play a big role for Barca this season but will not be involved when the Ronald Koeman era begins at the John Cruyff this weekend against Nastic.
