The Argentinian goalkeeper was stretchered off after a collision during Chelsea’s visit to Everton, and later underwent a surgery.
Goalkeeper Emi Martinez says he will be “back in a few weeks” after undergoing surgery following a clash of heads during Chelsea’s 2-0 win at Everton in the Premier League.
Martinez and Branthwaite came together when Everton’s Kiernan Dewsbury-Hall whipped a free kick into the box and, although the defender was back on his feet after treatment, the Argentina goalkeeper required treatment from paramedics.
The 34-year-old was eventually strapped to a stretcher and carried off the field before being taken to hospital with a concussion, as Argentine media reported he had suffered a jaw injury in the collision.
Martinez, wearing a hospital gown, posted on social media early on Sunday: “Thanks to everyone for the messages. The operation went well.
“The most important thing is that we won and kept a clean sheet. In a few weeks we’ll be back.”
Martinez’s injury forced Chelsea manager Xabi Alonso to give Mike Penders his Premier League debut, and the 21-year-old keeper helped Chelsea keep their first clean sheet in the league since January.
Penders, a Belgian youth international, will likely have to step in until Martinez is cleared to return to training.
Chelsea host Tottenham Hotspur in the league next Saturday followed by a League Cup fourth-round game at Liverpool on October 28 and a home Premier League match against Manchester United three days later.
