Chelsea goalkeeper Emiliano Martinez has undergone successful surgery on a fractured jaw following a clash of heads during a 2-0 win at Everton.

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

Martinez was treated on the pitch for eight minutes and eventually stretchered off to a waiting ambulance.

The 34-year-old posted on X on Sunday that the "operation went well" and vowed that he would be back "in a few weeks".

Chelsea also confirmed in a statement: "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 earlier played his part in Chelsea's win that also earned the team their first Premier League clean sheet in nine months.

Chelsea boss Xabi Alonso said after the game: "What we know is he left the stadium conscious and right now he is in the hospital doing 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."

Portugal winger Pedro Neto scored at the beginning and end of the second half for his first Premier League double.
