Ashley Williams is recovering in a Los Angeles hospital following surgery on a collapsed lung.
The Wales captain suffered the injury after breaking ribs during the goalless draw with Mexico on Tuesday in a collision with Javier Hernandez.
It was the 33-year-old’s first outing since playing for Everton in a Premier League game with Burnley on March 3.
Part of a statement from the Toffees read: “Everton medical staff are in contact with Williams and the medical team of the Football Association of Wales and it is anticipated that the 33-year-old defender will make a swift and full recovery.”
Posting on Facebook from his hospital room, Williams said: “[It’s been a] crazy couple of weeks.
“[It was] great to be back in a Wales shirt and with the lads. However, after coming off after 20 minutes with multiple breaks on two ribs, I went to hospital & found out I had punctured my left lung which led to it collapsing.
“I would like to say a huge thank you to all the staff at Ronald Reagan UCLA hospital in Beverley Hills for looking after me and making sure surgery went as comfortable as possible. Look forward to flying home and resting up now before the new season.”
