Chelsea have been rocked by the news that Spain winger Pedro has suffered multiple fractures to eye socket and cheekbone.
The 29-year-old wideman was on the receiving end of a challenge from Arsenal keeper David Ospina during the first half of the Blues 3-0 win over the Gunners in Beijing and will now miss the Community Shield.
He was taken to hospital as the rest of the squad moved on to Singapore where they are facing Bayern Munich on Tuesday night.
The club had initially feared he had suffered concussion. But he will be out for 10 days and will then wear a mask.
He is expected to rejoin his team-mates in Singapore this week.
Antonio Conte said: “With Pedro the situation was more serious because I hoped it was only concussion. He had a multiple fracture but with a mask, in 10 days he could come back to work with us.
“It was more serious as I thought it was only a concussion. But I think he needs one week to 10 days to recover very well and then to wear a mask for a period.”
Conte insisted he does not hold Ospina responsible for the injury.
He added: “I was a player and know it was accidental. It can happen, Ospina tried to take the ball.”
On Saturday evening he wrote on social media: “What a shock! Fortunately everything is ok. Thanks for your messages.”
