Changes have to be made to the Blues although the shape and identity of those alterations remain uncertain.
Signs suggest selections will be restricted for Saturday's Dunedin match with the Highlanders.
"We have a soft underbelly because we are not disciplined enough," coach John Kirwan said.
His squad had apologised for their lack of application against the Brumbies and was determined to remedy that effort against the Highlanders.
"Many things are good like our defence which is running at 93 per cent," Kirwan said.
