Kiwis coach Stephen Kearney says the decision to pull Simon Mannering out of the upcoming England tour was taken to "protect" the long serving skipper.
On Thursday afternoon Kearney confirmed that Mannering, who has missed just one Warriors game in the last three seasons, would not be making the trip.
Mannering has been plagued by illness this year and while his condition is not thought to be serious, he had not sufficiently recovered from an outgoing gastric issue.
"Tests haven't confirmed a major issue but he hasn't really got any better," said Kearney. "It's [been done] to protect Simon.
It's taking the decision away from him. He would want to get away on tour...to try and do what is best for the team in whatever condition he is in. He can be his own worst enemy in that sense."
