Ange Postecoglou said Dejan Kulusevski 'should be okay' after being forced off early in Sunday's 2-0 loss against Crystal Palace.
Playing in a forward role with Dominic Solanke and Richarlison rested, Deki went down feeling his knee after a collision with Marc Guehi on 15 minutes. He came back on briefly after treatment but was replaced by Mikey Moore on 19 minutes.
Speaking to the media afterwards, Ange said: "He should be okay, just talking to him after. The medical team are not too concerned with him, more of a knock than anything else, so we're hoping he should be okay."
Positive news saw the return of skipper Heung-Min Son after a foot injury kept him out of our last seven matches, he came off the bench for Pedro Porro on 58 minutes.
"It was good to get him some match minutes and hopefully we can get him some more match minutes against Villa on Friday," said Ange. "It would be good to get him back, involved and available."
