David Moyes says veteran defender Seamus Coleman is back available for selection for the clash with Manchester United on Monday.
The Republic of Ireland international has not played in the Premier League since November.
“Seamus [Coleman] is fit and available as well, so we’ve got people we can choose and we’ll move on from [O’Brien’s red card],” Moyes said. “He got sent off and these things happen.
“We’ve got everybody fit, bar Jack Grealish.”
The Everton boss also says he is encouraged by what he has seen from youngster Tyler Dibling, who has been left as an unused substitute for the last two league games.
“I think he’s one who we think we’ve got a really good, talented player on our hands,” Moyes said. “We need him to develop and get used to us a little bit.
“He’ll probably need a little bit of time. Even me looking towards the start of next season, I’m saying pre-season friendlies etcetera, all those things will help get him more established than when we got him in.
“Look, he’s beginning to learn a lot more about us. He’ll get game time I’m sure between now and the end of the season, so it’s good.”
