Jagielka will have to watch from the sidelines until the New Year.
Everton captain Phil Jagielka has been ruled out for up to four weeks after suffering a hamstring injury.
Jagielka missed Everton’s 2-1 win against Southampton in the Premier League on Sunday as a result of a problem he originally sustained in Thursday’ loss against Sunderland at Goodison Park.
Toffees boss Roberto Martinez confirmed at his post-match press conference after the victory over Southampton that the England international may not be back in action until late January.
“It was at the end of the game against Sunderland,” Martinez said.
“With this soft tissue injury it could be up to four weeks, but knowing Jags he will be back earlier.
“It is just the accumulation of games and the demands of this month. November into December is high-risk in terms of injuries to the players.
“When you have the number of games we play, it is understandable.”
