All Blacks captain Richie McCaw will undergo tests over the coming days to determine his availability this weekend after being momentarily knocked out in the Crusaders' victory over the Blues on Saturday.
Crusaders coach Todd Blackadder said whether McCaw will face the Hurricanes in a crucial New Zealand Conference clash on Saturday will depend on test results.
"There are a set of procedures that will be followed by a doctor and if he passes them he will should be fine [to play]," Blackadder told Radio Sport.
"He looked pretty good in the sheds but we'll see how he rolls out."
