His ODI performances backed up the tests where he was joint man of the series with Alastair Cook. Boult took 13 wickets at 24.84.
That test workload of 116 overs, plus seven matches in the Indian Premier League as an $814,000 acquisition for the Sunrisers Hyderabad has been significant.
This is not the first time Boult has suffered back problems. He was diagnosed with a stress fracture after making his debut tour with New Zealand to Australia in 2009.
In other team news, Colin Munro comes into the New Zealand squad as a replacement for Corey Anderson. Munro has been playing for Worcestershire on a country contract. He joins the squad for the final two ODI games and the T20.
Last night England won the toss and batted in the third match at Southampton. Left-arm pace bowler Ben Wheeler made his debut as the country's 185th ODI cricketer.
