Arsenal have confirmed that Petr Cech is set to be out of action for up to a month with a hamstring injury.
The goalkeeper limped off in the 2-0 win over Watford at the Emirates at the weekend and had to be replaced by Bernd Leno.
After the match Arsenal boss Unai Emery said: "I think it's a hamstring. Maybe he will miss two or three weeks. I hope not more."
However, a medical update on the club's website confirmed that the 36-year-old is facing up to a month on the sidelines.
The statement said: "Left hamstring injury. Expected to return to full training in 3-4 weeks."
Cech has made seven Premier League appearances this season, with Emery utilising summer signing Leno in the Europa League and Carabao Cup so far before his first league appearance from the bench on Saturday.
Watford created several opportunities after the break but Leno denied the visitors with some good saves.
"I'm very happy with Leno," said Emery. "I think he was content to wait for this moment and now it is arriving. His performance was the best for us today."
