Everton defender Phil Jagielka is to have surgery on a badly gashed ankle, manager David Moyes has confirmed.
Jagielka, 30, was injured during the first half of the 3-1 Premier League win against Reading following a challenge from Adam le Fondre.
He had to be immediately replaced, and Moyes said: "I genuinely haven't seen it again but I thought on the pitch it didn't look good.
"Jagielka knew about it and it is a bad one. He will have surgery tonight to stitch up his ankle. It is a bad one because he is a key player for us."
