Loose forward has developed delayed symptoms Versatile Shannon Frizell brought into squadAll Blacks loose forward Luke Jacobson has been ruled out of the Rugby
World Cup due to a delayed onset of concussion and will be replaced by Shannon Frizell. The 22-year-old Jacobson had played just 20 minutes off the bench against
Argentina before he was named in the squad for the tournament.
He came off the bench against Tonga on 7 September and did not suffer any issues until the All Blacks arrived in
Japan and he developed symptoms after their first training session.
