Pedro Neto scored both goals as Chelsea beat Everton 2-0 in the Premier League on Saturday, BBC Sport and Sky Sports reported. Neto struck in the opening minute of the second half and again in the 90th minute, BBC Sport reported. It was his first Premier League double, in his 187th appearance, according to BBC Sport.

The win was marred by a head injury to Chelsea goalkeeper Emiliano Martínez, The Guardian and Sky Sports reported. He collided with Everton defender Jarrad Branthwaite while challenging for a free kick and needed lengthy treatment before being carried away with his neck in a brace, The Guardian reported. He was taken to hospital for tests, The Guardian and Sky Sports reported, and The Guardian said he had a suspected concussion. No diagnosis has been announced.

"When he left the stadium he was conscious," Chelsea manager Xabi Alonso said, according to The Guardian. "Hopefully it is not too bad but we need to wait." Mike Penders, 21, made his Premier League debut as Martínez's replacement, BBC Sport reported.

Neto's first goal came after Jorrel Hato's cross took a touch off James Tarkowski, The Guardian reported. His second followed a free kick that bounced off several players before dropping to him, the outlet reported. Moisés Caicedo hit the crossbar with a volley before halftime, The Guardian and BBC Sport reported.

The result was Everton's first defeat of the league season, The Guardian and Sky Sports reported. Chelsea kept their first league clean sheet since January 17, ending a run of 22 games conceding, BBC Sport reported. Everton manager David Moyes said, "We just didn't create enough," according to The Guardian.

Chelsea's Morgan Rogers escaped a sending-off before halftime, Sky Sports reported, and The Guardian said he was "extremely fortunate to avoid a second yellow card."
