Aaron Cruden, one of the All Blacks' four World Cup flyhalves, doesn't need surgery for the knee injury which forced him out of the Final against France in Auckland last Sunday.
Medical updates on All Black captain Richie McCaw and fellow flyhalf Colin Slade are not yet available.
All Black doctor Deb Robinson said on Saturday Cruden should make a full recovery after hyper-extending his knee 34 minutes into New Zealand 8-7 win over Les Blues in the Final.
Robinson said Cruden saw an Auckland specialist on Friday, who confirmed the All Blacks pivot wouldn't require surgery.
"He'll have to wear a knee brace for the next three to four weeks before he gradually returns to training over the following month, and is expected to make a full recovery," Robinson said.
That should see Cruden cleared to play a full part in the Chiefs' Super Rugby campaign where he will link up with his Manawatu coach Dave Rennie and All Blacks assistant Wayne Smith.
Rennie, who has taken the reins after Ian Foster's eight-year term, felt his side had enough cover anyway.
Southland recruit Robbie Robinson has spent plenty of time in the No.10 jumper, and the Chiefs have also signed Hawke's Bay goalkicker Andrew Horrell.
The coaches go into the draft room early next week before the squads are announced on Wednesday.
Rennie, who will be joined at the franchise by former All Black defence and counter-attack coach Wayne Smith, leaves for overseas immediately after finalising his squad. He intends to use the draft to shore up his midfield and outside back contingent.
Midfield will not be such a pressing issue if Sonny Bill Williams becomes the 28th player signed by the Chiefs ahead of the draft.
Rennie remained coy on the prospect of Williams joining his ranks, saying he had received some "feedback" in the past 24 hours, but would not say whether the feedback was positive.
"If he goes overseas or goes to the Blues, we've got someone else in mind."
The Chiefs have signed 27 of their 28 squad positions.
