Loose forward Brad Mika remains in the frame for a belated Blues call-up.
The 30-year-old former All Black was a surprise pick for this season's squad but damaged a knee before the tournament and then snapped his Achilles tendon.
It is almost seven months since his operation and while not yet at full strength, Mika has passed inspections from the Blues medical staff.
He is expected to be named in the squad today as franchise sides are revealed for 2012's expanded series.
"It's come along well and while I have not quite got a full heel extension it is making good progress," he said.
