Everton boss Roberto Martinez says Bryan Oviedo's injury was not serious.
The Costa Rica full-back was stretchered off in the 71st-minute of the game at Chelsea, with replacement Ramiro Funes Mori going on to score Everton's third.
But Martinez insisted there are no major concerns over Oviedo and that he will be monitored over the rest of the weekend.
“Bryan's injury is not serious and he should be ok," said the Blues boss. “We will assess him over the next 24 hours.
“It was more a knock rather than anything else. We expect that Bryan will be ok."
