The Argentina international collided with Everton centre-back Jarrad Branthwaite as the pair challenged for a cross on Saturday.

After more than eight minutes of treatment on the pitch at the Hill Dickinson Stadium, Martinez was carried off on a stretcher before being transferred to an ambulance.

The goalkeeper later shared a photo of himself in a hospital bed on Instagram, writing: “Thank you for all the messages, the operation went well.”

He added: “We’ll be back in a few weeks.”

Speaking after the match, Chelsea boss Xabi Alonso confirmed Martinez had been taken to hospital for “precautionary tests”.

"It was concussion but more than that I saw only one clip. Hopefully it won't be too bad but we need to wait."

Chelsea later confirmed the surgery in a statement, saying: “Goalkeeper Emiliano Martinez has undergone successful surgery on a fractured jaw.

“Everyone at Chelsea wishes Emi a speedy recovery and will support him throughout.”

Martinez had earlier helped Chelsea secure a victory that ended their nine-month wait for a Premier League clean sheet.

His replacement, 21-year-old Belgian goalkeeper Mike Penders, made his Premier League debut and helped Chelsea secure their first top-flight clean sheet in 23 matches.
