Lions captain Sam Warburton is staying with the squad but will play no further part on the field.
A hamstring tear’s ruled him out of the deciding test.
Sean O’ Brien is one of those who could take his place in the back row, while Brian O’ Driscoll is expected to take over as captain.
Meanwhile the fate of the opposing skipper James Horwill is still up in the air.
He’s waiting on the verdict of an appeal hearing over his alleged stamp on Alun-wyn Jones in the first test.
