The Selhurst supremo said after the Brentford win: “I can’t tell you (about the severity of Olise’s issue).
“I spoke to him and he didn’t seem overly concerned. I spoke with the doc and he wasn’t shaking his head to suggest that he [Olise] needed a scan tomorrow and we might have to fear the worst – he wasn’t doing that.
“We don’t know until he gets back into training and we assess it. It would be really unlucky. I don’t think it was a major snap of a muscle, but unfortunately, we’re in that period of football life where you’re playing 20 games and with three games in a week, so I’m afraid people are going to pick up muscle injuries.”
Everton earned a 3-2 victory against Palace at Selhurst Park when the two sides met in November.
