The Blues loss to the Waratahs in Sydney has come with an extra cost as they have lost prop Charlie Faumuina for the next six weeks.
The Blues returned to Super Rugby after their bye and lost 30-27 to the Waratahs taking them to back to back losses as they lost to the Bulls before the bye.
Seven test cap tighthead prop Faumuina suffered a grade two right calf strain midway through the first half in Sydney, but he will have an ultrasound scan on Tuesday to assess the full extent of the injury.
In the meantime the Blues medical team have decided to keep him on crutches.
Angus Ta'avao, who came on for Faumuina at Allianz Stadium, shapes as the most obvious replacement for Saturday's blockbuster clash with the Chiefs, while Ofa Tu'ungafasi also provides cover at tighthead prop.
The Blues face the Chiefs at Baypark Stadium, Mount Maunganui on Saturday.
