Crystal Palace could be missing former Clarets loanee Gary Cahill as well as defender Joel Ward for the game at Burnley.

Boss Roy Hodgson is definitely without full-back Ward due to a "serious knee injury" and could have another casualty for the Clarets clash.

Ex-Chelsea defender Cahill, who had a successful spell at Turf Moor in the 2004/05 season, trained on his own on Thursday and had an ice pack on his knee afterwards.

Hodgson will hope Cahill is fit enough to play, but will definitely be missing Ward and does not expect him to feature again until 2020 after suffering the problem going in for a challenge with Liverpool's Divock Origi.

"You know how doctors and medical staff are, they are reluctant to put a date because they are frightened you are going to come back after a period of time and demand the player returns," Hodgson said.

"But it is a serious knee injury in the sense it will keep him off for a number of weeks rather than a number of days.

"I can't tell you exactly what the timescale is, but it will be a considerable amount of time."

In Ward's absence, Martin Kelly - who worked with Hodgson at Liverpool - is likely to earn a recall and make his first start since October 5.

Once an England international, the 29-year-old is comfortable playing at the heart of defence or on the right, which is where he will line up this weekend.

"Kelly was a right-back by profession when I worked with him at Liverpool and when I took him to Euro 2012 it was as a right-back," Hodgson added.
