An update from the club read: "Newcastle United defender Sven Botman will undergo surgery next week after suffering a knee injury against Manchester City.
"Following further assessment, a scan has confirmed that he sustained an injury to his ACL during Saturday's match and he is expected to return to action within six-to-nine months.
"The Dutch centre-back initially sustained a knee injury in September 2023 and elected for a non-surgical rehabilitation plan - a decision which saw him return to action in December.
"Everyone at Newcastle United wishes Sven a full and speedy recovery."
