Everton manager David Moyes has claimed that he will try to find a solution following the injury blow to midfielder Darron Gibson.
The Republic of Ireland international has been ruled out for up to five weeks after suffering a thigh injury while on duty during his side's 2014 World Cup qualifiers.
"It is a concern for me because he has been very consistent and very good," said Moyes. "It is a blow but we will have to find ways of getting around it."
Meanwhile, the Scottish boss has offered his support to the families of the Hillsborough tragedy victims.
