Chelsea boss Mauricio Pochettino is hopeful of Mykhaylo Mudryk's injury not being serious after victory at Fulham.
Mudryk and Armaando Broja struck for the visitors to ease pressure on Pochettino and his players.
But the Ukraine winger was withdrawn at halftime and Pochettino later explained: "He was doing well.
"[It is] unlucky that at half time he felt something in his quad but we hope that it is not a big issue and he will be ready for Saturday."
Pochettino also offered an update on Moises Caicedo: "Caicedo was a contusion but also hopefully it's nothing wrong. He was tired, but it was a contusion. "
