Chelsea goalkeeper Emiliano Martinez was stretchered off following a sickening collision with Everton defender Jarrad Branthwaite.

The players appeared to clash heads as Martinez came off his line to collect a cross into the Everton box, with Branthwaite attempting to reach the ball.

There was immediate concern for both players as they stayed down in the box, but Branthwaite was able to return to his feet after a couple of minutes.

Martinez, however, stayed down on his box as Chelsea physios and medical staff worked with caution and the stretcher was called.

The Argentinian was eventually carried off to pitch to applause from the Chelsea supporters at Hill Dickinson Stadium, following a period of around 10 minutes.

Martinez appeared to be moving his arms while he was stretchered straight down the tunnel, in what appeared to be a positive sign.

He was replaced in the 73rd minute by Belgian reserve goalkeeper Mike Penders, who came on to make his Premier League debut with Chelsea leading 1-0.

Branthwaite was cleared to continue for Everton after team physios performed concussion checks on the pitch.
