Blues recruit Otere Black will miss the majority of next year's Super Rugby season after rupturing his anterior cruciate ligament for Manawatu.
Black, who signed with the Blues through to 2019 from the Hurricanes this year, injured his knee in Manawatu's 46-25 Ranfurly Shield loss to Taranaki in New Plymouth on Wednesday night.
Manawatu coach Jeremy Cotter confirmed first five-eighth Black had done his ACL; an injury which typically requires six-to-nine months recovery. The Super Rugby season starts in late February and runs through to July.
Black is now the most experienced playmaker on the Blues' books and was, therefore, signed to guide the team from next year.
Taranaki first-five Stephen Perofeta will now be favoured to start at No 10 for the Blues, with North Harbour's Bryn Gatland likely to deputise.
