Blues first-five-eighth Stephen Perofeta has been called into the New Zealand under-20 rugby team for their world championship final against England in Georgia early on Monday (NZT).
Blues first five eighth Stephen Perofeta during the Blues vs British and Irish Lions match played at Eden Park.
Perofeta replaces Tiaan Falcon, who has been ruled out after he was concussed in the Baby Blacks' 39-26 semi-final win over France.
Alex Mitchell from Taranaki has also joined the squad as a replacement for Ryan Coxon at prop.
New Zealand coach Craig Philpott says it is disappointing Falcon won't be able to play in the final.
"Luckily we have an awesome replacement in Stephen, who played for the under-20s last year and brings a wealth of experience."
Philpott said his forwards had delivered consistently throughout the tournament, and would need to step up against England.
"Our scrum and lineout has been operating at close to 100 per cent during the tournament, so we need to reproduce that in the final."
