Chelsea manager Enzo Maresca announced on Friday that Cole Palmer will be sidelined for an additional six weeks.
The England midfielder has been unavailable since Chelsea’s 2-1 loss to Manchester United on September 20, during which he left the pitch in the first half.
Maresca had initially expressed hope that Palmer, 23, would return following this month’s international break.
“I was wrong. Unfortunately, he needs to be out for probably six more weeks. So, yes, this is the update,” he said.
The Italian coach said that he was optimistic the forward would not need surgery.
Maresca, whose team face Nottingham Forest on Saturday, said replacing “one of the best players in the Premier League” was difficult.
