Moder suffered ACL damage during a goalless draw against Norwich back in April and was ruled out for a “significant period of time”.
The Poland international, who is expected to miss this winter’s World Cup in Qatar, has undergone a further procedure after experiencing joint stiffness during his rehabilitation.
The club have described the additional operation as “common” for what they say is a “complex” injury, but have given no updated timescale for his return beyond the new year.

David Weir, Brighton’s technical director, said: “Jakub’s initial diagnosis was a very complex and severe injury to his knee and we always felt it was unrealistic to expect him back before the end of this calendar year.
“The club’s management and medical team has involved Jakub in all decision making on his treatment and rehabilitation plans, and he recently spent six weeks back home rehabbing in Poland.
“On his return to England he experienced some stiffness and restrictions in his movement as he stepped up the rehab, so underwent a second surgical procedure to alleviate the issue.
“This is a common procedure that is required when dealing with such a significant trauma to the knee.
“We fully appreciate the desire to be available for the World Cup, but we have always been clear that the chance of this was always very slim. His rehab is still following the timescale that we originally envisaged.”
Moder has made 40 league appearances for Brighton since joining from Polish side Lech Poznan in 2020, with 28 of those coming in the 2021-22 campaign.
