Everton boss Sean Dyche is confident Dwight McNeil's injury isn't serious.
The winger broke down during last night's 0-0 draw at FA Cup opponents Crystal Palace.
"He is OK and we'll just let that settle down," said Dyche.
"The immediate sign is better than we thought. It's an ankle injury.
"It's early but Dwight is in the dressing room and calm, which is a good sign.
"Hopefully it's a swollen ankle, but it's too early to tell."
