Everton goalkeeper Tim Howard will be sidelined for up to six weeks with a calf injury. The 35-year-old United States international initially missed Sunday's loss at Newcastle with the injury sustained against Stoke on Friday. Everton manager Roberto Martinez says ''Tim Howard will be out between five and six weeks with a calf injury.'' Joel Robles will play in Howard's absence, and Martinez says he will assess whether Everton needs to sign another goalkeeper. Howard's injury is a further blow for Everton, which has lost three consecutive matches heading into Thursday's game at Hull.
