Corey Anderson will play no further part in New Zealand’s tour of England due to a back problem that has restricted his involvement since the first Test. Anderson will return home for further assessment on the stress-related injury.The news will also come as a blow to Somerset, with the county having signed him as one of their overseas players for the NatWest T20 Blast.Anderson was recovering from a finger fracture when he arrived in England from the IPL but featured in the Lord’s Test, scoring a counterattacking half-century in the second innings. He was only able to bowl eight overs, however, and missed the second Test and the first two ODIs.An MRI scan subsequently revealed a “bone stress related injury to his lumbar spine”, which requires investigation, ruling Anderson out of the remaining three ODIs and T20.”Corey has been working hard to get back to full fitness for the ODI series but he hasn’t been able to overcome this injury,” New Zealand’s coach, Mike Hesson, said. “We felt the best course of action was to send him back to New Zealand for further assessment.”New Zealand have not yet called up a replacement to their 15-man squad.
