Medical checks have revealed that the back rower has a gastric problem, and will need to stay at home for treatment.
“While tests we’ve conducted haven’t revealed anything to cause alarm, Simon still isn’t right to and requires further assessment,” NZ Warriors head doctor John Mayhew revealed.
His withdrawal means Kiwis coach Stephen Kearney will soon have to name another skipper for his squad.
“We know Simon wants to be with us and this decision will be a huge blow for him, as it is for us,” said Kearney.
“He’s our captain and our leader, but we’ll still have a strong leadership team to draw on and his absence this time will give us a chance to develop some other players in that role.”
