Everton manager Roberto Martinez has revealed that defender Phil Jagielka will be out of action for up to four weeks with a hamstring injury.

The Toffees captain was absent during his side's 2-1 home victory over Southampton in the Premier League on Sunday.

"It was at the end of the game against Sunderland," Sky Sports News quotes him as saying.

"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."

Everton are currently five points behind leaders Arsenal in fourth place.
