Everton midfielder Abdoulaye Doucoure is battling a fresh injury setback.
Doucoure was back after four games out with a hamstring injury when he played a full 90 minutes against Aston Villa in the Premier League.
But in Wednesday's FA Cup replay against Crystal Palace, the midfielder was missing again.
A match Everton won 1-0 despite the absence of the 31-year-old.
After the match, manager Sean Dyche admitted: "It's a hamstring injury, but in the other leg. It has nothing to do with the other injury.
"It's the same with Seamus (Coleman), i.e. a minor hamstring problem. We hope they recover quickly, but it is still too early to say anything about."
