James Garner faces more than two months out of action as he attempts to overcome a back injury.
The midfielder missed the Premier League game at Bournemouth with what was initially described as a knock. It was confirmed he had suffered a back issue and he was absent from the squad that travelled to Australia for the Sydney Super Cup. It is hoped he will be available around the end of January or beginning of February.
Frank Lampard has received better news over Tom Davies and Yerry Mina. Both picked up injuries on the trip but neither are as bad as first feared.
