All Black flanker Sam Cane's playing comeback from a shocking neck injury could begin against the Blues in Auckland this Saturday.
Chiefs coach Colin Cooper said Cane was "going really well" and his comeback "could be this week or next".
The Chiefs play the Reds in Hamilton next week.
Cane suffered a neck break during a test in South Africa last October, meaning a race against time to find his form and fitness for this year's World Cup.
The 27-year-old was operated on in Pretoria, with two vertebrae being fused together and wrapped in metal. Specialists reported there was no nerve damage.
