The 22-year-old will be out of rugby for at least a week.
North Harbour back Saili was one of three wider training group players who assembled with the squad ahead of The Investec Rugby Championship, along with Wellington lock Jeremy Thrush and Counties Manukau winger Frank Halai, with these players returning to their ITM Cup teams on the Wednesday of each Test week.
Crotty will train with the All Blacks before the World Champions head to Sydney on Thursday ahead of the opening match of the tournament in Sydney on August 17 this weekend.
The 24-year-old Canterbury midfielder will likely then return to his provincial team along with Thrush and Halai.
The selection of Crotty, although in the wider training group, is an important one for the inform centre, whose stock rose dramatically during Investec Super Rugby when he shifted from second five-eighth to centre to cover for Robbie Fruean.
