Jordan will have surgery, which will see him spend at least six months on the sidelines - also ruling him out of the AllBlacks tests against England and Fiji in July.
“After assessment from the Crusaders medical team, he will undergo surgery and as a result be unavailable for selection during the 2024 Super Rugby Pacific season,” the Crusaders said in a statement.
“He is expected to be fit to return to play in approximately six months.”
The 25-year-old missed the start of last season due to an inner ear issue, returning for the Crusaders’ run to an 11th Super Rugby title.
It’s a major blow for the franchise, which lost the likes of Richie Mo’unga, Sam Whitelock and Leicester Fainga’anuku in the off-season, while new signing Leigh Halfpenny will likely miss the season.
The defending champions open the season against the Chiefs on Friday night in Hamilton.
