Tim Howard will be out of goal for Everton for up to six weeks with a calf injury.

Everton will turn to Joel Robles with Howard out.

"Tim will be out for between five and six weeks," said Roberto Martinez. "It is an injury to his left calf. As a goalkeeper it's really unusual to get an injury by kicking a ball."

Everton's only other goalkeeping options are 18-year-olds Russell Griffiths and Jindrich Stanek, who have both never played a senior game for the club.
