Frank Lampard has confirmed James Garner is expected to be out for around two months with a back injury, with Tom Davies and Yerry Mina likely to return to training in December.
Midfielder Garner missed Everton's final Premier League match at Bournemouth before the World Cup break with his back problem, and Lampard believes the summer signing from Manchester United will be available again "at the back end of January or early February".
Fellow midfielder Davies was forced to leave Everton's tour to Australia after sustaining a knee injury during a training session in Sydney. After returning to England to be assessed, the Academy graduate is set to return in three to four weeks.
That is a similar timeframe to centre-back Mina, who picked up a hamstring problem during the Blues' win over Celtic on Sunday.
When asked about the trio, Lampard told evertontv: "Tom is three weeks-ish, which is a positive result as we were worried about him.
"Yerry is similar, three to four weeks.
"Unfortunately, James Garner is going to be more than that. He’s probably going to be back at the back end of January or early February. It’s a disappointing injury."
